To avoid this confusion about squid, we call squid (in standard configuration) a forward proxy, and haproxy (or nginx, or apache w/ mod_proxy module) a reverse proxy. Based on what you described, you're probably looking for a reverse proxy with SNI awareness. SNI allows the reverse proxy to run different rules based on Host: header in the request. Apache calls this named-based virtual hosts.

Based on the initial description you want multiple domains routed through 1 external IP and probably the standard port 443. Normally what I'd do here is SSL offload at a reverse proxy with a cert with all the domains as SANs that has the IP (or NAT) and route to my backend services using named-based virtual hosts.

There are other options. If you could break down exactly how you want the traffic to arrive and where you want the rules, the list of technologies will narrow itself down.

If you want, I can do a more specific containers presentation and be more specific on the configs for multiple domains on my 1 IP. (The nginx + ssl part that I didn't present on)

Yes, you can use NAT, and in fact, I need to, because my servers don't use root ports.
But that doesn't affect the domain/subdomains selected.

Can this also be done with NAT built into pfsense
any chance this could be done as a class at one of the meetings
