Run sshd on multiple ports but different domains

Question

I want to run my sshd server on multiple ports but different domains.

The server should be reachable as following:

ssh -p 12345     example.com
ssh -p 22    git.example.com

I tried to modify /etc/ssh/sshd_config like this:

Port 12345
ListenAddress 0.0.0.0
ListenAddress git.example.com

But that's not working.

You could also do something with iptables to shuffle the ports around.

ssh does not care so much about domains. It just listens on an ip:port combination. Its up to you to make the domains point at the right ip.
