A router can forward a single port to a single destination only, but the destination can usually include a custom port. What I mean is you can usually setup port forwarding on a router as:<br />
<br />
Router_public_IP:3022 --&gt; Server1:22<br />
Router_public_IP:4022 --&gt; Server2:22<br />
<br />
If you can setup your router like this you don't need to change the port of openSSH on the server.

changing the port on open SSH.

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.
