2 systems sharing internet with usb modem, is it possible?

[joki]

hi
My brother has 2 systems which he wants to network together and share with 1 internet connection. the problem is, he only has one of those useless usb modems in which to do it with. Is it possible to use router software on the one main system, and route the data through it & onto the internet. My concern is that the usb modem does not have an interface in which i can set an ip address.

Thanks
