@kate I already have my IRC server irc.mills.io running behind Caddy Layer 4. However I don't terminate TLS at the edge in this case.

@prologic I got confused as one can simply proxy through Caddy. Duh! 😅

@bender How do you mean? 🧐 Caddy doesn't do L4 by default.

@prologic right, it doesn’t. It is a module.

@bender Yup 👍

@prologic want to share the snippet of your Caddyfile for irc.mills.io?

@bender Sure! 👍

{
    ...
   # Layer 4 Reverse Proxy
   layer4 {
      # Gopher
      0.0.0.0:70 {
         route {
            proxy <internal_ip>:70
         }
      }

      # IRC (TLS)
      0.0.0.0:6697 {
         route {
            proxy <internal_ip>:6697
         }
      }
   }
}

@kate You're welcome 😇
