  • Nginx Reverse Proxy game hosting
    2 projects | /r/selfhosted | 9 Jan 2023
    Wireguard gives my service servers their own internal IP for the gateway to reference (nothing fancy done with it, no iptables modifications like you may see on other guides), and I use NGINX for the game server proxying, specifically linuxserver's nginx container. I love Caddy, but even with caddy-l4 I couldn't get it working right for Valheim (and thus UDP), but NGINX worked real quick.

    Well, that's a bit off-topic from the parent comment, which was more about the Caddyfile supporting complex config (versus the underlying JSON config) and not really "complex usecases".

    But that said, from a quick Google search... was this an RTMP stream? If so, I suppose you'd want to use https://github.com/mholt/caddy-l4 which is a plugin for Caddy that lets you do TCP-layer things. Caddy's standard distribution just ships an HTTP server (plus TLS and PKI, etc), which is layer-7

    You might be able to use caddy-l4's "tee" handler to pipe into multiple "proxy" handlers. But I'm not sure anyone's tried this yet, I had no idea people did this sort of thing. I'd be interested to hear if it does work though.

  • Brand new to this, have a few questions about DDNS, reverse proxies, etc
    2 projects | /r/selfhosted | 18 Jun 2022
    If you are only having your services accessible via LAN, HTTPS isn't totally necessary, but I would still recommend it. I think a reverse proxy will be easier than your described method. Just set it to listen to 443 and have all of your other services on random ports being proxied from the reverse proxy. If you want HTTPS from your reverse proxy to your services, most reverse proxies will have this kind of feature. Here is the caddy L4 raw TCP stream module: https://github.com/mholt/caddy-l4
  • Alternative to SRV record?

    I had a similar problem a while back and found this project (Caddy-L4). It had no releases or examples on how to build it so I forked it and added some Docker stuff.

    "Caddy L4" aka "Project Conncept" might be what you're looking for:

    https://github.com/mholt/caddy-l4

    "Project Conncept is an experimental layer 4 app for Caddy. It facilitates composable handling of raw TCP/UDP connections based on properties of the connection or the beginning of the stream."

  • I'm Using SNI Proxying and IPv6 to Share Port 443 Between Webapps
    6 projects | news.ycombinator.com | 23 Apr 2022
    Nice, this is kind of why I made Project Conncept. It's a powerful TCP and UDP stream multiplexer based on Caddy: https://github.com/mholt/caddy-l4

    You can route raw TCP connections by using higher layer protocol matching logic like HTTP properties, SSH, TLS ClientHello info, and more, in composable routes that let you do nearly anything.
