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
you only have one IP. As you rightfully said, reverse proxy does only http(s), port 80/443. this works because of the nature how http requests work. They carry the hostname as part of the protocol (request headers). SSH is a whole other story, since the client does not send the hostname as part of the protocol, only the IP and the port.
What you can do is forward different ports to different machines… 2021 -> server1, 2022 -> server2, etc.

For SSH the
ProxyJumpdirective is awesome. Have one server reachable from outside and then use it to jump to all the others.
