Join the public network so it's reachable by systems on our LAN, # The priv_lan network is already setup, so it is an 'external' network, Grant cloudflared permission to bind to a privileged port, Configure cloudflareds Prometheus metrics (optional), Point Pi-hole to the new IP of cloudflared. I have found the auto-renewal of Synology Lets Encrypt certificates to be temperamental (also Synology have yet to support the more robust. The filenames dont matter, but I tend to name mine using the following structure cloudflare.mycustomdomain.crt and cloudflare.mycustomdomain.key. If you love Pi-hole, consider donating its ongoing development. 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. Hopefully Synologys forthcoming DSM 7 update may provide a better interface to easily add this functionality, without the need for shell access and custom scripts. Tunnel connection to docker container - Cloudflare Community Create a Free Cloudflare Tunnel - Learn With Omar - GitHub Pages The script used an updated API, Cloudflare API v4. I got this going easy enough. 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. Please check your network settings." 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! Thanks James, glad it was useful! Use your Synology admin account to connect. 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. Load balanced highly available Cloudflare tunnels with Docker Swarm cloudflared (DoH) - Pi-hole documentation This is not helpful, so we can fix that by setting an environment variable TUNNEL_METRICS=0.0.0.0:49312 to bind to all interfaces on port 49312. Now we could choose to just select Flexible or Full from the options available. Part 1: Are you feeling LUKy? Docker Hub However, make sure you check that compulsory https does not cause issues with your server (especially if enabling preload under HSTS, as you will not be able to remove compulsory https quickly if HSTS preload has been setup). 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. In fairness though, the same applies to the Cloudflare Origin Certificate. Set up your first tunnel Cloudflare Zero Trust docs 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. They both follow the convention of http:///dns-query for the lookup URL. Tested this in DSM 6.2. You will need to click Add button, choosing the Add new certificate option before clicking Next as shown below. We would rather not give more data to Google, and we want to use DoH. 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 ). 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. There was a problem preparing your codespace, please try again. Cloudflare One is the culmination of engineering and technical development guided by conversations with thousands of customers about the future of the corporate network. 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). So, how do I make sure there's a DNS resolver available to the Pihole when it starts up? All Rights Reserved. Nevertheless, it is possible to set up a Synology provided sub-domain and generate your own auto-renewing trusted SSL certificate for this sub-domain within the Synology interface, as this video explains. Pi-Hole & DNS-over-HTTPS in Docker - Michael Dodd Traditional DNS is insecure and requests can easily be spied on or modified. Synology has a Docker distribution for their devices, which was a great start. The links to the certificate can be found on the following page. Pi-hole and cloudflared with Docker - Michael Roach Effectively your site will have to run everything over https, and it is not easy to reverse this quickly. 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 i just used the docker command they recommended. Cloudflare will tell you the names of the servers to use as part of the setup process. 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). Downloads Cloudflare Zero Trust docs Any hints here? For example, I found this not to work on a Synology 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. We need to make some changes to the configuration for this setup to work. Automate Docker Container Updates on Synology NAS - Baihu Qian The final step is to download Cloudflares Origin CA root certificates the exact type depending on whether you opted for an RSA or ECDSA origin certificate. Thanks for the update on ECDSA, Ill change that in a sec. For the readers, to change the port go to Control Panel > Network > DSM Settings > DSM Ports and change your HTTP and HTTPS ports to supported ones. 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! When setting-up Pi-hole, it needs to be configured with the DNS servers it will use to resolve non-blocked requests. Any ideas how I can resolve this so it works through CF? I did some amalgamation of both, and the container keeps crashing. However, in some instances this simply isnt possible, given that Cloudflare will only proxy traffic sent over the http protocol. In the examples to follow, well say our real network is 10.65.2.0/24 and our router is 10.65.2.1. 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. 2:48 Set the right. This solution proposed is complete with a Docker-compose.yml file that basically solves what I'm looking for. Cloudflare One is the culmination of engineering and technical development guided by conversations with thousands of customers about the future of the corporate network. The instructions from the cloudflare site for docker are: $ sudo docker run cloudflare/cloudflared:latest tunnel --no-autoupdate run --token . container_name: cloudflared. Cloudflares Origin CA Root RSA Certificate, https://support.cloudflare.com/hc/en-us/articles/200169156-Which-ports-will-Cloudflare-work-with-, https://github.com/mrikirill/SynologyDDNSCloudflareMultidomain, 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=, https://www.cloudflare.com/en-gb/products/tunnel/, https://developers.cloudflare.com/cloudflare-one/tutorials/ssh/, Part 2: Are you feeling LUKy? 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). 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 evidenced in the below diagram which shows padlocked (encrypted) traffic from the browser to the Cloudflare Servers (the edge part of the connection), and similarly for the proxied traffic to our origin server. There, you will get a single line command to start and run your cloudflared docker container authenticating to your Cloudflare account. I really do like Docker Compose. Cloudflared + Synology DSM - cannot upload larger file? Securing a Raspberry Pi using a Zymkey4 Hardware Security Module. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. When Cloudflare receives a request for your chosen hostname, it proxies the request through those connections to cloudflared. Click Next to continue. I wanted to map volumes so the config info was stored outside of the container for easy updates. Ensure you can SSH into your Synology NAS. Seems great ! It is important you understand the implications of this action for non-https traffic. I will try soon the part with intermediate certificates in order to pass to Full (stricit) mode. By default this is using Google DNS. They are also registered on the US Privacy Shield Framework, which at the point of writing, helps with GDPR compliance. Since cloudflared is now a dependency of Pi-hole in our setup, well use docker-compose to orchestrate this. Thank you Edward and Jordy! 1:10 Download container image. 2. UPDATE Ive since been informed that ECDSA is no longer supported by DSM 6, so youll need to choose the RSA option. If you use VLANs on your network, macvlan supports binding to VLAN tagging.

You can then use it to expose: The set up process will require you to migrate your domains nameservers over to theirs. 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. Its a DNS server that subscribes to blocklists to block advertising and tracking services at the network level. # but do not expose pi-hole to the internet! 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. Disclaimer: I have never setup a WARP to Tunnel network. 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. DNS over HTTPS prevents this by doing what it sounds like: sending your DNS requests over a secure HTTPS connection. For HTTP, its not a big deal to use other ports, like 8080. restart: unless-stopped. I have quite a few containers running, including Pi-Hole and cloudflared Home Assistant HomeBridge Trying to make a Google login API. Pi-hole works by subscribing to various blocklists. The macvlan documentation shows how. Do you have any suggestions or tips how to overcome this challenge? Create an account to follow your favorite communities and start taking part in conversations.

Once youre set up and Cloudflare has registered the nameserver switch, you are free to start configuring the SSL settings. 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. You could then redirect your Cloudflare DNS to this subdomain through the use of CNAME record, providing full-strict SSL for your website. 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. You can just ssh into your NAS and run the standard command. Synology Community Join the internal network so Pi-hole can talk to cloudflared, # 2. The Cloudflare SSL interface has settings for two types of certificate the Edge (proxy-server) certificate, and the origin (your servers) certificate. Trying to MCPatch a 1.7.3 Beta instance. mounted share on a NAS). 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. However, Flexible only secures the first part of the chain (from the browser to Cloudflare) the traffic sent from Cloudflare to our server not being encrypted. If you for any reason don't want to use docker you can use normal daemon instead . Wiring up the basics Synology has a Docker distribution for their devices, which was a great start. Installing this was straightforward using the usual mechanism. Setting up Cloudflare with a Synology NAS - Cross Connected 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). Given this adds an additional level of complexity I am not going to cover the Authenticated Origin Pulls feature in this article. This is a problem though with DNS since DNS has to be responding on port 53. For those who dont know about Cloudflare, they are an American web-infrastructure and website-security company offering a variety of services at differing cost brackets. For this reason, you will need to access Pi-hole using your Synology NAS's IP address and a defined port. Your email address will not be published. autonomous management of my SSL certificates I had found Synology DSM to be temperamental with its automatic renewal of Lets Encrypt certificates and I wanted something that was largely set and forget. We can inform Docker of this topology in a network called priv_lan that the host is connected to on interface eth0. If you continue to use this site we will assume that you are happy with it. This is of course a very desirable feature, but it is quite complicated to setup within the current Synology interface. We bind the DNS service to 0.0.0.0 to so it listens on all interfaces. Until fairly recently, this would have required purchasing of a certificate, rather than the use a free self-signed certificate. Deploy your app using just a single docker command without having to setup a reverse proxy nor a single port forwarding. Create a secrets directory owned by root with mode 600, and any values you need to keep secret like your CLOUDFLARE_API_KEY, etc. You can also add custom blocklist rules. These samples offer a starting point for how to integrate different services using a Compose file. In this guide well setup cloudflare and Pi-hole together with docker-compose to create a portable and reproducible secure DNS solution. 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 . Setting up CloudFlared in docker - MindlessTux Thanks for the tip on the DDNS. This article has been invaluable in helping secure it with Cloudflare.

Arguably QuickConnect also offers some of this, but you cannot use your own custom domain, a free caching service helping reduce the load on my server. Watchtower was a good choice, and there's no shortage of resources that discuss how to run this on a Synology (including another resource at Marius Hosting). Things were good, but then I wanted to do network-wide ad blocking (to deal with ads on streaming devices), but found that even if I specified an additional DNS server, the router would still advertise itself as a DNS server, as well as any additional DNS server I added. Sometimes I would have secure DNS, sometimes not. The is a script to be used to add Cloudflare as a DDNS to Synology NAS. I just found out that cloudflare has a free tier. Note, the private key will only be displayed once in this window, and it is not password protected/encrypted.
