We just got our new Wireless 2.4mbps connection today and I got it working on Linux via pppconfig. Unfortunately the device is connected via USB and I'd like to share the connection with 2 other computers in the home via ethernet. Is this possible and how would it be done?

The computers the connection would be shared with would be windows.

PS: I'm used to plain DHCP DSL and this ppp thing is totally new and I imagine it might be a task setting this up!
