It is also wise to replicate your DNS records before making the switch to make the transition as smooth as possible (just make sure you proxy any record that points to your servers IP). command: tunnel --config . This internal network will be 172.30.9.0/29. Pi-hole works by subscribing to various blocklists. In turn, cloudflared proxies the request to your applications. I will try soon the part with intermediate certificates in order to pass to Full (stricit) mode. Edward, thank you so much for such an excellent, well explained article. This stemmed from an issue within Pihole, where it had Google's DNS selected as the upstream DNS servers even though the DNS servers were defined as part of the environment variables. Ive tried it myself on my NAS but I found some limitations for my functionality. The following window will appear. 1:10 Download container image. It also assumes you are using a custom docker network named 'proxy'. In fairness though, the same applies to the Cloudflare Origin Certificate. Effectively your site will have to run everything over https, and it is not easy to reverse this quickly. For devices on your network to use Pi-hole as their DNS server, youll need to make some configuration changes. # This allows Pihole to work in this setup and when answering across VLANS. 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! For this reason, you will need to access Pi-hole using your Synology NAS's IP address and a defined port. If you love Pi-hole, consider donating its ongoing development. 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. You can then use it to expose: I am currently completely revamping my home theatre setup using the built in reverse proxy server and some Docker containers. 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. For example, I found this not to work on a Synology NAS. This is a multi-arch image and will run on amd64, aarch64, and armhf devices, including the Raspberry Pi. 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). This all worked really great, until Watchtower updated Pihole. 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. Once generated, Cloudflare will ask the format for your certificate signing request (CSR) and private key choose PEM and proceed to copy the resulting text values into two separate text files. 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. DNS over HTTPS prevents this by doing what it sounds like: sending your DNS requests over a secure HTTPS connection. It works perfectly fine when accessing it through the NASs internal IP so has something to do with CF. You should now have three files your origin certificate, your origin root certificate, and your origins private key. Installing this was straightforward using the usual mechanism. I wanted to map volumes so the config info was stored outside of the container for easy updates. Neon - Serverless Postgres, open-source alternative to Press J to jump to the feed. To update Plex Media Server, go to the status/activity icon on the top-right corner. Now we could choose to just select Flexible or Full from the options available. 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. And it's pretty awesome. Flexible container deployment If any manual configuration is done to Pi-hole, that should probably be shared or synchronised between Pi-hole servers in a way that doesnt add points of failure (e.g. 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. 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. 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. 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). 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). The script used an updated API, Cloudflare API v4. The links to the certificate can be found on the following page. LUKS stands for LinuxUnifiedKeySetup and it is actually a key Read more. If I were setting this up now, Id probably use a Cloudflare Tunnel, which can also be used to proxy SSH traffic, as explained here: https://developers.cloudflare.com/cloudflare-one/tutorials/ssh/ The main benefit of Tunnels, over the steps Ive outlined above, is that you dont have to port forward/open ports on your router, so provided you trust Cloudflare, its even more secure. The is a script to be used to add Cloudflare as a DDNS to Synology NAS. If you continue to use this site we will assume that you are happy with it. docker-cloudflared-tunnel is a Docker image based on Cloudflare Argo Tunnel solution which provide Cloudflare daemon ad-hoc capabilities through Docker. Type a description for the certificate (for example Cloudflare Origin domain name) and keep the Import certificate option checked. 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. Introduction and core concepts docker-cloudflared-tunnel is a Docker image based on Cloudflare Argo Tunnel solution which provide Cloudflare daemon ad-hoc capabilities through Docker. Once youve added/selected your chosen values, Click the blue next button to generate your Origin certificate. Cloudflare will tell you the names of the servers to use as part of the setup process. 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. These docs contain step-by-step, use case driven, tutorials to use Cloudflare . Certificate the certificate signing request you generated, Intermediate Certificate Cloudflares Origin Root CA file you saved, using the most up-to-date protocols the clients browser supports (note, for Cloudflares free accounts, ciphers are set based on your choice of protocol as listed, implementing policy mechanisms to guard against SSL Stripping and Man in the Middle attacks, enforcing SSL for all traffic (this is optional), setting the Minimum TLS Version to 1.2 this ensures only modern TLS protocols are used, setting Opportunistic Encryption to On this allows the client to benefit from HTTP/2 performance features if available, setting TLS 1.3 to On this enables the latest TLS protocol, if the clients browser is compatible, setting Automatic HTTPS Rewrites to On this helps to protect against mixed content errors (but note it doesnt necessarily rewrite all http links to https), configuring HTTP Strict Transport Security (HSTS) this is one of the more obscure and hardest to set up settings, but arguably also one of the most important settings (to avoid SSL stripping and man in the middle attacks, as, reading and accepting the acknowledgement deceleration shown after clicking the blue Change HSTS Settings button, Enabling Enable HSTS (Strict-Transport-Security), Enabling Apply HSTS policy to sub-domains (includeSubDomains). 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. 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. the web servers in use, the number of virtual hosts, and whether or not local network access is required). You could then redirect your Cloudflare DNS to this subdomain through the use of CNAME record, providing full-strict SSL for your website. 2:48 Set the right. 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. use a local VPN (for example Synology NAS VPN services) to access any services that dont need to be exposed via port forwarding. Will Synology Drive, Backup station etc still work? Pi-hole with cloudflared provides a powerful security and privacy enhancement to any network. You signed in with another tab or window. 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. No more punching holes in the firewall and opening stuff directly to the internet, plus the ability to give specific people/friends access to only the resources they need. Technology. 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. When testing that I was actually using Secure DNS and DNSSEC from Cloudflare's check tool, I would see inconsistent results. Hi Jordy thanks, glad you like it! Traditional DNS is insecure and requests can easily be spied on or modified. Just need a bit more lifting to get there with a couple more steps. Trying to make a Google login API. We value your privacy. Run commands in Synology I wanted for the cloudflared to come up via docker-compose or as a stack in the swarm. 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). 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. You can just ssh into your NAS and run the standard command. 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. They both follow the convention of http://
