In response to the discussion on a recent thread about whether to trust Cloudflare, as some people are not very comfortable with it terminates HTTPS (MITM).
There is this thing called Fast Reverse Proxy (FRP) https://github.com/fatedier/frp
It’s open source, very lightweight and I have used it in multiple instances. Frankly there doesn’t seem to be a lot of people know/use it here. The idea is you deploy this on a VPS with public IP, and have your server at home connect to it. It is pretty much like your own Cloudflare tunnel, only you have much more control over it (ports, TCP/UDP/HTTP, auth, etc).
I use it on the cheapest VPS ($5) I can find close to where I live. It acts as a simple TCP reverse proxy to my server, where Nginx Proxy Manager handles the actual HTTPS. (You can let FRP handle HTTPS but then you need to think about if you trust the VPS and also keep the certs updated there, so nah.)
It’s developed by a Chinese dude as it is pretty much a necessity for selfhosters (mostly minecraft servers) in China, since Public IP is scarce there and most people live behind CGNATs.
Personally, when I used to route my home services through a VPS- I used a simple VPN tunnel from my VPS to my home network, which my home router would establish (dynamic IP).
From there, my firewall dictated what was actually allowed to enter through the tunnel… and the reverse proxy, did its thing.
This type of tool is interesting, and provides some of the functionality that Cloudflare Tunnel does, but with frp, a vulnerability in your app (or its login screen) could be more easily exploited since you don’t have the traffic protection features that Cloudflare provides, right? Maybe combining this with fail2ban (or is there another similar self-hosted tool) would not only act as a proxy but also help protect your app to a degree like Cloudflare does?
This is just the kind of tool to get me back to this
I’m assuming the benefit over say Caddy + Authelia is that you don’t need to open any local ports such as 80 and 443?
I use this for all my services that need to be accessible from the outside world… For my private services I use tailscale + headscale
Use a reputable self-hosted VPN, for example https://blog.trailofbits.com/2016/12/12/meet-algo-the-vpn-that-works/ (Trail of Bits is one of the top auditor/security company)
Isn’t cloudflare tunnel a reverse proxy too?
Well, pretty much any type of tunneling software such as Tailscale or Wireguard will achieve the same, you just need to change a bit where your components are located.
What I personally do is have swag proxy on the VPS with crowdsec and authelia, this redirects the traffic to the internal wireguard/tailscale mesh network to the specific service requested.
If you are the only user of the services, create a tailscale or a netmaker; Not sure about tailscale but in Netmaker (wireguard based) you can choose to have your VPS as the relay host.
Frp is a pretty cool tool, I mostly use Tailscale with a Reverse Proxy on a VPS for my remote access, but I tunnel my Minecraft Servers using frp, since it’s lower latency and more stable than Tailscale. For Websites I couldn’t notice a difference, and Tailscale + Caddy worked easier for me than frp
I use this and cloudflare. For my normal self hosted app’s cloudflare works great but for stuff that needs a lot of data (Plex) or custom ports I route I through FRP.
My choice was Caddy v2 and wg_easy as well as a Python script which updates the IP if changed automatically. My own dyndns if you will
I just use a vpn
So a VPN and a reverse proxy, any can be combined this way
Why do you really need this ?
Why not just set up a VPS and deploy the NginxProxyManager to it together with a wireguard tunnel to your home system.
You really dont need 2 proxies…
Or if you want to keep the NPM localy on your home server, then you just setup wireguard on VPS with NAT and port forward to your tunnel.
I think a lot of proxy servers have that functionality, HAproxy definitely has… With nginx you need the “plus” Version to proxy tcp.
