Re: ssh port - two instances?
I was once tasked to run two ssh daemons on one system.
It did not come out very well.
I do believe that it is possible to get the one daemon to listen on two ports.
That would be by modification of the sshd_config file.
Take a look at these articles:

intra?

Have they offered to do NAT/PAT to translate
a port of their choice to your port 22? If
they're creating the problem, I'd suggest an
opportunity for them to solve it.

Re: ssh port - two instances?
This brings up another idiosyncracity of the network/firewall admins. In this day and age, they still think obscurity can provide security. What if you listen to port 65531 for an external ssl connection ? Port-scanners only take another few seconds to find that vulnerability and if you, the firewall admin, is incapable of doing very rudimentary screening of source IP address and what not, to determine the authenticity of the TCP packet, regardless of which port you listen to, you will get hacked. I am sorry to say but this is a very sloppy way of refusing service to address a (what looks like) legitimate business need. (off my soapbox now)

Re: ssh port - two instances?
No you don't want to open the firewall and most firewall admins would never go with that.
This might help limit system exposure:
