I am not sure quite what you are trying to achive.. But...

You only need 2 intefaces.. One external on Internal. The external of
course is the ADSL PCI card and the Internal is the network card...

Any machines that run services that need a static 'internet' address
have a port forward. Which is NAT'd to the Internal box. This is
standard firewalling...

So.. Any traffic hits the external card has a port number. The firewall
rules recognizes the port and forwards the traffic to the correct box..

External 195.8.69.12 -> Port 25 (SMTP) -> Forward to 192.168.42.1.

Make any sense? Is this even what you are trying to do?
