2 machines connected how to share Internet using fixed IP ?

[keevill]

I have 2 machines , 1 running Win7 and the other WinXP. They are connected to a network switch.
I have configured both with fixed IP addresses as I want to share some folders on the Win7 machine for the WinXP machine.
This works.
I can connect to the Internet using a USB air card which also works fine.
How can I share the Internet connection for the WinXP machine ?
If I try to use ICS, it is not possible to use fixed IPs.

correct ICS will want to do all the address assignments, you will have to remove the static IP for this.

Then if I remove the static IP's, how can the machines connect to each other ?
There is no DHCP server.

ICS will act as a DHCP


just as an FYI, windows computers XP and beyond will start up with an Automatic Private Internet Protocol Address (APIPA).

so if you took a bunch of windows computers hooked them to a switch, they would be able to talk just based on their APIPA addresses.

ICS will surely work as a DHCP too as J_RaD said, it will assign ip to your second computer
