I'm assuming you're talking about talking to two people on a remote LAN, 
and that LAN uses NAT to connect to the internet.

The first question is - who's connecting to whom?

If the remote systems are connecting to you, then there's no problem. 
However, if you are trying to connect to them, there's a lot more work 
involved.  The router must be set up with port forwarding and you have 
to connect to the correct port to forward to the proper machine.

You can find more information in a TCP/IP newsgroup.
