Can anyone tell me how to setup windows xp pro as a router?

I have gone into the registry and switched on ipforwarding.

Basically i have 2 different networks 192.168.0 and 10.0.0
I have a laptop with a standard 10/100 nic and wireless.

The wireless is setup with mask gw

The nic is mask gw ?

i'm not totally sure about the gw of the nic.

anyway what do i have to do to it to route from the 10.0.0 -> 192.168.0 network so i can access the internet?
