Port forward to different IP based on destination address

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?
