Do I need 2 network card and 2 fixed IP address to set up a VPN server?

When I set up my VPN server on Windows 2003 Server, it said I need to have 2 network cards. Ok, I installed another network card and configured the VPN server. I have a fixed IP in my office and the Netscreen firewall is between the VPN server and the internet. The firewall use the IP of 192.168.0.1 and the server has to use 192.168.0.2 inorder to work with Netscreen firewall. Do I need to type in my real IP for the network cards? Right now, I have it on auto. If I type in the real IP then it will have conflict with the firewall setup. Also, I have 2 network cards, so I need 2 fixed IP for the 2 network cards? I am really confused! What is the proper procedure to set up a VPN. I have checked the Microsoft documentation and it's not covered.

Thanks for the help in advance!

As you know I have a Netscreen firewall and the ports opened are 21,23,25,110,80. Can I use one of these ports instead of 1723 ? Can I configure this in the VPN Server?

So, how do I configure the VPN to use let say port 25 instead of 1723?
