Hello all you lovely people!

I’m trying to figure out if I can port forward to different servers based on the destination domain.

I have a domain with a wildcard cert and I’d like to be able to route all traffic headed towards “1.domain.com” to a server I’m calling “1”. I’d still like traffic headed to domain.com to go to where it’s currently going, we can call this server “0”, and to be able to have a 2.domain.com or 3 or 4 in the future.

I thought that having a port forward rule with: interface: WAN Protocol: any source: any destination: a url alias including 1.domain.com redirect target ip: local ip

Would work, but it doesn’t seem to. Any tips?

    I think you can achieve it with a reverse-proxy. Let’s say that domain.com points at server 0, you’ll have to put a reverse proxy that answers all calls. In the config of the reverse proxy you’ll have to redirect the services based on the domain. I’m using Caddy and this example should work:

    0.domain.com {
                        reverse_proxy http://X.X.X.X:8080
                      }
1.domain.com {
                        reverse_proxy http://Y.Y.Y.Y:8123
                        }

    And so on.

    EDIT: Looks like I was late to the party! +1 to @greco reply as it’s more complete and clear (especially on the risks of this approach)
