Verizon EVDO Network into Internal Network

[johnnyBravo1]

I have a laptop with a verizon aircard and also have a PC with Verizon Aircard. My laptop is going to be mobile and my PC is win XP Pro is going to be acting as a gateway to my internal network. I want to be able to get access to my internal network . Both the aircards can ping each other. So here are the configs for both the laptop and XP PC.
(Verizon Aircard)Laptop IP: 166.139.19.40 Subnet: 255.255.255.255 Gateway:166.139.19.40
(Verizon Aircard)XP PC IP: 166.155.36.100 Subnet: 255.255.255.255 Gateway:166.155.36.100
Internal XP PC IP: 10.4.2.11 Subnet:255.255.0.0 Gateay: 10.4.1.254

My question is how would I request something on the 10.4.x.x network and have it be routed through the XP pc from the laptop?

thanks for any help in this subject.

You need to set up a static NAT on the XP PC that points 166.155.36.100 to the 10.4.x.x host that you want to get to. Don't ask me how you do this with Windows. It is a simple IPTables rule on Linux.

For every given port, you will only be able to interface with a single internal socket (IP and port). They don't have to be the same on the external NAT address and the internal host. For instance you could define a NAT rule that would forward 166.155.35.100:8080 to 10.4.2.10:80 and get a web server. At the same time, you could have a rule that forwards 166.155.35.100:8081 to 10.4.1.1:80 to connect to its web server.
