That's not true either. You can set up SSH to listen on any port you
care to choose (assuming that it's not already in use). So you can set
up different ports for each PC you want to access.

On many home routers, you can also forward from one public port on the
router to a different port on a computer on the local network.
Personally, I find it easier not to bother, at least with SSH -- keep
the port numbers consistent throughout, then you've got one less
variable to worry about.

Hope this helps,
