If you for any reason don't want to use docker you can use normal daemon instead . In turn, cloudflared proxies the request to your applications. There is also an additional step you might wish to consider (Authenticated Origin Pulls) within the Origin Certificate settings page of Cloudflare. For these devices to use Pi-hole, you need to update the DHCP server configuration. The macvlan documentation shows how. the use of wildcard certificates (not currently supported by Synology DSM 6 for Lets Encrypt). We need to make some changes to the configuration for this setup to work. So now weve set up our origin certificate on our Synology device, I would advise you to make the following tweaks to ensure that (where possible) we are: To tweak the settings we need to navigate to navigate to the Edge Certificates settings within Cloudflare administration pages for your domain (found under the SSL/TLS menu and Edge Certificates menu, as shown below). Dump Quick Connect and use your own domain to connect to your Synology NAS securely using Cloudflare proxy and SSL through Nginx Proxy Manager. Subscribe!h. This setting allows your server to cryptographically validate that a web request is coming from Cloudflares servers, stopping circumvention of Cloudflares security measures if your servers IP is accidentally leaked. Using the zero trust dashboard I began to create a tunnelI gave it a name and chose the location to install the cloudflared tunnel connectorI chose docker.I coped the command line that was . Docker Samples: A collection of over 30 repositories that offer sample containerized demo applications, tutorials, and labs. container_name: cloudflared. Pihole has a docker image, so it was a matter of configuring this. Please check your network settings." To help you decide, an explanation of the workings and pros and cons of elliptical curve certificates can be found in this article (note either RSA or ECDSA will work with Synology DSM 6). Your email address will not be published. So, the goal is simple: Run Docker on the Synology, and run PiHole as a container. As such, you will need to consider the security implications of disclosing your servers IP address (something Cloudflare will notify you about if your DNS records expose your IP). So I am a newbie here and I wanted to set up a Cloudflare tunnel to my docker instance on my synology nas. Docker on the Synology starts the container back up, but since nothing has really changed, the same issue occurs again. This is desirable as firewall rules and lock out events may be effected if our server is not seeing the request IPs, potentially having undesirable security implications. For devices on your network to use Pi-hole as their DNS server, youll need to make some configuration changes. This article will take you through the steps I followed to set up my Synology NAS, using Cloudflare to proxy my web traffic and secure in-transit connections to my server. I currently work with CloudFlare and a Synology at home but not using only Full mode (simple). I think these existed back when I wrote the article, but they only become a free service as of April 2021. We can check the logs to make sure everything looks good: Another option is to skip using the internal network and instead directly attach cloudflared to our real network. restart: unless-stopped. The script used an updated API, Cloudflare API v4. Flexible container deployment Users of Synology products should be allowed to enable SSH for any user and for admin accounts they could add sudo privilege so they can do administrative tasks. We want to ensure all our certificates are authenticated to help reduce the risk of man in the middle (MITM) attacks hence why I have chosen Full (strict) which validates all the certificates in the chain. Hi Fabio, great, glad you found this tutorial useful! Deploying configuration with something like Ansible could be a good solution. I have personally chosen to do this, as nearly all my traffic comes via Cloudflare, and in instances where it doesnt (for example my VPN which cant be proxied using Cloudflare), I set a different certificate for this using an alternative domain. UPDATE Ive since been informed that ECDSA is no longer supported by DSM 6, so youll need to choose the RSA option. Move the docker-compose.yaml file that you created to the folder of the container that you'll be creating. '/volume1/docker/pihole/dnsmasq.d/:/etc/dnsmasq.d/', '/volume1/docker/pihole/pihole/:/etc/pihole', "TUNNEL_DNS_UPSTREAM=https://1.1.1.1/dns-query,https://1.0.0.1/dns-query", /var/run/docker.sock:/var/run/docker.sock, WATCHTOWER_NOTIFICATION_EMAIL_SUBJECTTAG=Hostname, WATCHTOWER_NOTIFICATION_EMAIL_FROM=# Valid sender, WATCHTOWER_NOTIFICATION_EMAIL_TO=# Valid Recipient, WATCHTOWER_NOTIFICATION_EMAIL_SERVER=in-v3.mailjet.com, WATCHTOWER_NOTIFICATION_EMAIL_SERVER_PORT=587, WATCHTOWER_NOTIFICATION_EMAIL_SERVER_USER=# Mailjet username, WATCHTOWER_NOTIFICATION_EMAIL_SERVER_PASSWORD=# Mailjet Password, "HA" Pihole between Debian, Synology and Docker. It is important you understand the implications of this action for non-https traffic. It is then down to you to select the services you wish to assign to the origin certificate (for example, Synology Drive Server and any Web Station virtual hosts). In fairness though, the same applies to the Cloudflare Origin Certificate. networks: - proxy. So when a browser tries to resolve ads.doubleclick.net, Pi-hole says: nope, doesnt exist. source: https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/install-and-setup/tunnel-guide poudenes February 12, 2022, 9:18am #2 After some more search I found this way how to do it directly on my NAS: Until fairly recently, this would have required purchasing of a certificate, rather than the use a free self-signed certificate. You can just ssh into your NAS and run the standard command. command: tunnel --config . Pi-hole and cloudflared relationship Docker macvlan DNS over HTTP Servers Option 1: Hidden cloudflared Internal network cloudflared Pi-hole pihole-compose.yml Testing Option 2: Attach cloudflared to the LAN Assign cloudflared an ip DNS port Metrics pihole-compose.yml Testing Next steps Configuration sync Blocking rogue DNS Adding blocklists Ensure you can SSH into your Synology NAS. --dns=127.0.0.1 --dns=1.1.1.1 The second server can be any DNS IP of your choosing, but the first dns must be 127.0.0.1. There are some limitations to this approach however: For the above reasons I chose instead to use an alternative Origin Certificate generated within Cloudflare for my domain. 0:58 Create folder. Most routers can be reconfigured to assign custom DNS servers to clients. Are you trying to connect via SSH? Awesome Compose: A curated repository containing over 30 Docker Compose samples. For HTTP, its not a big deal to use other ports, like 8080. If you go that route, CF will create the flattened CNAME record for you once they issue the "connection key". Well create it by hand so that this network is usable by any docker-compose setup and not just the one well create later: Note: When attaching containers directly to a network, port mapping has no effect (i.e. However, in some instances this simply isnt possible, given that Cloudflare will only proxy traffic sent over the http protocol. # This allows Pihole to work in this setup and when answering across VLANS. Pi-hole works by subscribing to various blocklists. The basis of this idea is that my Synology NAS is "probably" one of the first things I'm going to turn on, and one of the more "foundational" pieces of the network, so running network-wide services on the device is sound. The process varies wildly by router so I cant provide direction, but login to your routers If you love Pi-hole, consider donating its ongoing development. In my experience, as long as its http protocol traffic, this will allow you to use Cloudflare for services utilising unsupported ports. Ive tried it myself on my NAS but I found some limitations for my functionality. Incorrect preload configuration can expose you more than it protects you (as, to ensure your servers IP is kept masked via Cloudflares reverse proxy, you dont expose your server by opening up unnecessary ports, you use a firewall on your server that only allows traffic over essential ports and protocols, and where possible, limits traffic to only trusted clients. Press question mark to learn the rest of the keyboard shortcuts. If nothing happens, download Xcode and try again. Great work on this! It also assumes you are using a custom docker network named 'proxy'. Given this adds an additional level of complexity I am not going to cover the Authenticated Origin Pulls feature in this article. There was a problem preparing your codespace, please try again. "TUNNEL_DNS_UPSTREAM=https://1.1.1.1/dns-query,https://1.0.0.1/dns-query,https://9.9.9.9/dns-query,https://149.112.112.9/dns-query", # Attach cloudflared only to the private network, # Internal IP of the cloudflared container, # Explicitly disable a second DNS server, otherwise Pi-hole uses Google, # Listen on all interfaces and permit all origins. Plex updates are necessary in order to avoid bugs, improve performance, and overall security. For records that you cant proxy (for example MX records), if these point to your server, you may wish to consider using a relay service to be able to keep masking your IP (as discussed in this article). In this guide well setup cloudflare and Pi-hole together with docker-compose to create a portable and reproducible secure DNS solution. I got it working. Thanks for the tip on the DDNS. I did some amalgamation of both, and the container keeps crashing. This article has been invaluable in helping secure it with Cloudflare. Wiring up the basics Synology has a Docker distribution for their devices, which was a great start. Edward, thank you so much for such an excellent, well explained article. I have been using cloudflare tunnel (docker cloudflared) with a public subdomain set up for my Synology, and successfully used it to access DSM for a month without issue. We would rather not give more data to Google, and we want to use DoH. Are you sure you want to create this branch? We can verify that the cloudflared container is making this request by using: $ docker-compose -f "pihole-doh.yml" down to bring down the container and re-running the dig command. For those who need to assign the origin certificate to certain services, rather than making it the default, you will need to navigate to Control Panel -> Security -> Certificate, clicking on the Configure button as shown below. What is Argo Tunnel Now we could choose to just select Flexible or Full from the options available. I wanna run the newer version that doesn't require the json file and where I can add internal sites via the cloudflare admin console. Docker is a lightweight virtualization application that gives you the ability to run thousands of containers created by developers from all over the world on DSM. Note, the nameserver transfer process usually takes a few hours, but to propagate fully across the globe, youre probably talking at least 24 hours and maybe 48. mounted share on a NAS). The software on the Synology isn't terribly feature rich, and certainly doesn't help me with the adblocking function that I'm looking for (as well as defining custom DNS records for the network), but PiHole does. Setting Max Age Header (max-age) to the recommended 6 month value (unless youve enabled the preload option, for reasons explained below). image: cloudflare/cloudflared:latest #update the verion where necessary. If you use VLANs on your network, macvlan supports binding to VLAN tagging. Work fast with our official CLI. A while ago, I got really sick and tired of dealing with the hardware that Telus shipped me for my residential gateway, and so a new "internal" router was added. Hence it is important to save this somewhere secure. Using Docker on Synology NAS is quite straightforward and can be accomplished via a nice web UI. I have quite a few containers running, including Pi-Hole and cloudflared Home Assistant HomeBridge Just one note which might help others with a dynamic IP, while Davids guide you linked to was really useful, I eventually ended up using Kirills script (https://github.com/mrikirill/SynologyDDNSCloudflareMultidomain) as it made it much easier to add multiple domains and subdomains within the DSM UI. In laymans terms, this means the traffic sent from a browser to our server (via Cloudflare) is encrypted and authenticated using trusted SSL certificates at each stage of the journey. https://community.cloudflare.com/t/cloudflared-docker-on-synology/355419. I wanted for the cloudflared to come up via docker-compose or as a stack in the swarm. Trying to link one container ( jacket ) via GUYS I FINALLY FIGURED OUT DOCKER IM SO PROUD OF MYSELF. You will need to click Add button, choosing the Add new certificate option before clicking Next as shown below. Hi Jordy thanks, glad you like it! They both follow the convention of http:///dns-query for the lookup URL. If you have any devices with a manually-configured IP address such as a home server or NAS, youll have to update their DNS servers to point to Pi-hole. Thank you for this complete article. By default, cloudflared uses the DoH service of Cloudflare. Deploy your app using just a single docker command without having to setup a reverse proxy nor a single port forwarding. Honestly might be easier to create the tunnel through Cloudflare's ZeroTrust portal. Introducing our new WordPress Plugin Mail Integration for Office 365, Setting up Cloudflare with a Synology NAS, Self-hosting a Mail Server with a Custom Domain and Partial Redundancy Client Setup, an added element of security, by masking my servers IP address and providing basic DDoS protection. Now we could visit http://localhost or another user on the network can visit http://machine-ip-or-hostname. But, I'm guessing I need to pass some params to the container to make ti run as that. Now install the service via cloudflared 's service command: sudo cloudflared service install --legacy Start the systemd service and check its status: sudo systemctl start cloudflared sudo systemctl status cloudflared Now test that it is working! This solution proposed is complete with a Docker-compose.yml file that basically solves what I'm looking for. Some software and devices have DNS servers (usually Googles 8.8.8.8) hardcoded in them. I just found out that cloudflare has a free tier. This article is a little dated now though, as Ive since learnt about Cloudflare Tunnels (https://www.cloudflare.com/en-gb/products/tunnel/). < 1024). Once youve added/selected your chosen values, Click the blue next button to generate your Origin certificate. cloudflared gets the IP 172.30.9.2 and responds to DNS queries on the unprivileged port 5053. If we wanted to, we could have multiple Pi-hole instances running on the same machine, each with its own IP listening on port 53. With the internal network removed, we need to bring cloudflared onto the real network priv_lan and assign it the IP address 10.65.2.14. Their free service includes DNS management, a reverse proxy and basic DDoS attack prevention, as well as free modern SSL services to help secure your servers traffic. Synology has a Docker distribution for their devices, which was a great start. cloudflared provides another type of security with DNS over HTTPS. However, in the mean time, the best advice is: This is a good blog article. I created a cloudflare user and group, and gave it full access to /volume1/docker/cloudflared. the web servers in use, the number of virtual hosts, and whether or not local network access is required). Any ideas how I can resolve this so it works through CF? Pi-hole with cloudflared provides a powerful security and privacy enhancement to any network. I will try soon the part with intermediate certificates in order to pass to Full (stricit) mode. You might like to do a followup article with bot protection turned on as this will block some apps like DS-CAM from fully working (but can be mitigated with page rule to lower security on the websocket and API), Hi, Followed your guide which is great and works a charm (thanks), but Ive just setup a VM with the VMM and when trying to connect to a VM with the Connect button it loads the page but says Cannot connect to the server. Learn more. Will Synology Drive, Backup station etc still work? I changed it to the ones supported by Cloudfare https://support.cloudflare.com/hc/en-us/articles/200169156-Which-ports-will-Cloudflare-work-with- and it worked! Do you have any suggestions or tips how to overcome this challenge? Pi-hole is assigned the IP 172.30.9.2 on our internal network and gets attached to the real network with the IP 10.65.2.4. I then use this to create a reverse proxy on the Synology, forwarding this traffic to localhost on whatever port Syncthing is running (this tutorial describes how you do this within DSM). admin interface and look for LAN and DHCP options. And it's pretty awesome. As shown below, you will have the option of letting Cloudflare generate a certificate, or using your own self-generated certificate (I personally chose to let Cloudflare generate the certificate). The final step is to make sure the SSL/TLS encryption mode is set to full strict under the SSL/TLS Overview page of Cloudflare (as shown below). This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Run commands in Synology Then on the Photos and Drive IoS app, when you put your hostname in, add a :8443 to the hostname and select HTTPS and it will work. One of the use cases I was hoping the Zymkey could support was the ability to securely mount an encrypted external drive automatically at boot. Trying to make a Google login API. If you have a dynamic rather than static IP address, you will also need to add a custom dynamic DNS entry within the Synology DSM interface to update Cloudflare when your IP Changes. It provides secure, fast, reliable, cost-effective network services, integrated with leading identity management and endpoint security providers. # Persist data and custom configuration to the host's storage, '/mnt/app-data/pihole/config:/etc/pihole/', '/mnt/app-data/pihole/dnsmasq:/etc/dnsmasq.d/', # 1. I am currently completely revamping my home theatre setup using the built in reverse proxy server and some Docker containers. Create a secrets directory owned by root with mode 600, and any values you need to keep secret like your CLOUDFLARE_API_KEY, etc. cloudflared login Running the above command will launch the default browser window and prompt you to login to your Cloudflare account. In typical home setups, the router is also the DHCP server and by default will tell devices to use the router as the DNS server too; an all-in-one solution. Well for me, Cloudflare provided: To get started you need to set up an account with Cloudflare, opting for their free service (unless you want the web application firewall and other features). You will probably also have to write scripts to trigger at boot and after updates, to ensure your edits are not rewritten when your Synology updates or reboots. So, the goal is simple: Run Docker on the Synology, and run PiHole as a container. If nothing happens, download GitHub Desktop and try again. Pihole has a docker image, so it was a matter of configuring this. Use Git or checkout with SVN using the web URL. This is a problem though with DNS since DNS has to be responding on port 53. If you are using Synology's Firewall, ensure that you allow port 22 traffic. Synology does allow SAN lists within their Lets Encrypt interface, but restricts the length to a few hundred characters, significantly limiting the usefulness when managing several sub-domains. Indeed, it requires SSH access to edit raw files for NGINX and/or Apache the exact edits being specific to an individuals current setup (e.g. So why would you want any of this when Synology offers QuickConnect and can manage Lets Encrypt certificate generation and renewal? Click on "Server Update Available" to download the right software version. Also, we are going to use msnelling/cloudflared docker image because it has multi-arch support, so it can be deployed on ARM64/ARMv7 (such as Raspberry Pi etc). This site talks about using DNS over HTTPS from Cloudflare as the upstream DNS resolver for a Pihole, which has the added advantage of hiding your DNS queries from your ISP. Just need a bit more lifting to get there with a couple more steps. For real usage, get started by creating a free Cloudflare account and heading to https://dash.teams.cloudflare.com/ -> Access -> Tunnels to create your first Tunnel. Cloudflare does not support every port on their Proxy (orange cloud), thus setting this up for the default DSM port is impossible. Effectively your site will have to run everything over https, and it is not easy to reverse this quickly. You signed in with another tab or window. You need to navigate to click the Browse button for each of the entries. If you also opt for Cloudflare generation, you will be able to choose between either RSA (2048 bit) or the modern elliptical curve alternative (ECDSA) both very secure. Image Variants Usage Quick Setup: How to use Access Synology via SSH. So, well configure Pi-hole to direct all requests to our running instance of cloudflared. Open Control Panel, select Terminal & SNMP, and Enable SSH service. This is fantastic just what I was looking for thanks for putting the effort in to put this together! Note, the private key will only be displayed once in this window, and it is not password protected/encrypted. To my surprise, there was no tutorial/examples provided for this Read more, Background If you already know what LUKS and hardware security modules are, you can ignore this bit and head to What Will this Cover below. Since few devices support DoH, cloudflared acts as a proxy between traditional DNS requests and DNS over HTTPS. We can inform Docker of this topology in a network called priv_lan that the host is connected to on interface eth0. When Cloudflare receives a request for your chosen hostname, it proxies the request through those connections to cloudflared. It provides secure, fast, reliable, cost-effective network services, integrated with leading identity management and endpoint security providers. With macvlan, Docker can create a new network that generates MAC addresses for containers and lets them have routable IPs on our LAN. So, how do I make sure there's a DNS resolver available to the Pihole when it starts up? Join the internal network so Pi-hole can talk to cloudflared, # 2. This is fine, but for redundancy and diversity, well add the Quad9 DoH servers as well. Cool, works as designed.. right? However, the rise of the Mozilla Foundation backed Lets Encrypt initiative has allowed anyone the ability to access free, secure SSL certificates signed by a trusted certificate authority recognised by most major browsers. . In this setup, we create another Docker network named internal that both the cloudflared and Pi-hole containers are connected to. Ive had this blocked for years without any problems. The Cloudflare SSL interface has settings for two types of certificate the Edge (proxy-server) certificate, and the origin (your servers) certificate. Cloudflare also allows you to add entries for multi-level sub-domains not covered by the wildcard, as well as giving you a choice of expiry length (I chose the default 15 years, but the more security conscious may wish to choose a lower value). The problem is the cloudflare/cloudflared Docker image doesnt run as root so it wont have permission to bind to a privileged port (i.e. For higher availability on a LAN, the setup could be deployed to multiple Docker hosts and the IPs of the Pi-hole servers added to the DHCP configuration on the LAN. Thank you Edward and Jordy! A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control. This internal network will be 172.30.9.0/29. We value your privacy. Given traffic from Cloudflare is being proxied, we need to make sure our Synology NAS isnt logging Cloudflares Serer IP addresses, and is instead logging the IP address of the originating request. Installing this was straightforward using the usual mechanism. The URL its trying to access is: https://my.domain.com/webman/3rdparty/Virtualization/noVNC/vnc.html?autoconnect=true&reconnect=true&path=synovirtualization/ws/70e6f827-cc1f-43cd-b778-00fbf369c689&title=NS1&app_id=94930208-63f7-4a80-b7e3-2ed78e595da1&kb_layout=en-gb&v=2.6.0-12122&app_alias=. This is very easy to do, you simply navigate to the SSL/TLS settings for your domain within Cloudflares administration pages, selecting the Origin tab and then clicking on the blue Create Certificate button as pictured below. If you already ran the other docker-compose up, tear it down now: And check that Prometheus metrics are working: This setup provides a portable Pi-hole with DNS over HTTPS configuration. To log the correct IP address, we need to navigate to Control Panel -> Security and scroll down on the Security tab until we see the trusted proxies button. Tested this in DSM 6.2. This allows Pi-hole to talk to cloudflared without exposing cloudflared to the rest of the network. This great tutorial explains one way to achieve this. For example, I found this not to work on a Synology NAS. Since cloudflared is now a dependency of Pi-hole in our setup, well use docker-compose to orchestrate this. But, it's working. Run the following dig command, a response should be returned similar to the one below: By now many are familiar with Pi-hole. Full ensures all stages of the chain are encrypted, however, no validation is carried out on the certificate used for the second part of the chain (from Cloudflare to our server). Pi-hole is configured to use the internal cloudflared as the exclusive DNS server. It downloaded the new image, shut down Pihole, replaced the image and started it back up. Once youre set up and Cloudflare has registered the nameserver switch, you are free to start configuring the SSL settings. setting Always Use HTTPS to On (this ensures all traffic to your server is secured), enabling preload under the HSTS configuration. If you wish to use a split DNS for your network traffic, the lack of wildfire support, and character limits on SAN alternative names is pretty restricting if you have more than 5/6 sub-domains to manage. Its a DNS server that subscribes to blocklists to block advertising and tracking services at the network level. DNS over HTTPS prevents this by doing what it sounds like: sending your DNS requests over a secure HTTPS connection. Ive been trying to setup my Synology NAS with TLS on Cloudfare for about 2 days, and my problem ended up being the port, as pointed out by Jordy. Thanks James, glad it was useful! However, the way Ive got around it for Syncthing is to create a subdomain in Cloudflare (for example sync.mydomain.com, accessed over port 443). Our Support Techs suggest running a tunnel connected to a running docker container with Cloudflare's origin proxy server and Free SSL with this command: ./cloudflared tunnel --hostname domainname.com http://0.0.0.0:5003 Here, we use command tunnel and binary cloudflared to set up a connection between an open port. Required fields are marked *. I would recommend changing the following settings: If you wish all your websites traffic to be over https, I would suggest you also enable the following settings under the Edge Certificate settings page. The links to the certificate can be found on the following page. Use Cloudflare DNS (1.1.1.1, 1.0.0.1) with DNS-Over-HTTPS Start docker run -d \ --name Cloudflared \ -p 54:53/tcp -p 54:53/udp \ srod/cloudflared-doh Update A CRON job is implemented to update cloudflared on a daily basis at 2am Resources https://developers.cloudflare.com/1.1.1.1/dns-over-https/cloudflared-proxy/ I added some to stop ads showing up on my LG smart TV. This is the link that I found: https://community.cloudflare.com/t/cloudflared-docker-on-synology/355419 The instructions from the cloudflare site for docker are: $ sudo docker run cloudflare/cloudflared:latest tunnel --no-autoupdate run --token <mytoken> I did some amalgamation of both, and the container keeps crashing. These docs contain step-by-step, use case driven, tutorials to use Cloudflare . use a local VPN (for example Synology NAS VPN services) to access any services that dont need to be exposed via port forwarding. Your email address will not be published. Scuba diving. Docker CloudFlare DDNS This small Alpine Linux based Docker image will allow you to use the free CloudFlare DNS Service as a Dynamic DNS Provider ( DDNS ). By doing this, we gain the ability to bypass Pi-hole if desired and still have the benefits of DNS over HTTPS. Securing a Raspberry Pi using a Zymkey4 Hardware Security Module. But only allowing admins to use SSH forces us to open up our devices to bigger risks just to do non-administrative tasks that is very common to do over SSH. This is of course a very desirable feature, but it is quite complicated to setup within the current Synology interface. Tunnels are great for connecting one service (like your HTTP front ends) but perhaps WARP would be a better solution for connecting an entire network? , it needs to be temperamental ( also Synology have yet to support the more robust servers well!
