You should forward different ports for each softphone, and change
ports in each of them. As i remember, x-lite uses 5060 and 8000-8005,
so forward those to first computer, then change settings for x-lite on
second computer (5061 and 8006-8010) and forward them to second ip,
etc.

DMZ is just alias for "forward all ports to one ip", so not much use.

As alternative you can set up VPN on router and asterisk box, so
asterisk will treat all internal addresses as local.
