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

Run Caddy as reverse proxy for example : https://caddyserver.com/docs/caddyfile/directives/reverse_proxy#examples Syntax is pretty simple and Caddy can automatically do the SSL certificate handling for you as well. No need to install Certbot.
