Proxy and NT setup w/ cable modem

Here is the situation I need help with, this should be easy, maybe my brain's too foggy.

PC1: Windows NT 4 sp6a is the server
PC2: Windows NT workstation

Ok, assign local ip address 10.0.0.2 to PC2 and instruct to use proxy located at 10.0.0.1

But....how do I set up PC1 to have BOTH a local IP address of 10.0.0.1 and at the same time request from the DHCP server of my ISP an IP address for the internet connection???? It seems to me that it is either/or, I either specify an IP address and DON"T get one from the DHCP server, and hence do not get a connection, or I request one from the DHCP server, but can't tell the rest of the computers on the LAN that my server's primary ip address is 10.0.0.1

How do I solve this in windows NT?

Thanks.

 

does PC1 have two network cards?

 

The easy way is with a broadband router, but if you have two NICs, you set one to DHCP client and connect it to the cable modem, the other NIC is setup for your network.

 

Post to self!! Just after posting the request and leaving for work it came to me that I alreday had the answer on my own website! D'oh!

I'm only using one Ethernet Card, hence only one Interface! That means that the proxy that I should use has to have the functionality to create a second interface and assign a local IP address to it, such as 10.0.0.1 or....I get myself a second Ethernet card and use a simple proxy like the one from analogx.com
