I have an eee running ArchLinux with wireless access to the Internet. I want to use it as the WAN input for an Asus RT-G32 router into which it is hardwired. The router in turn is hooked up to a 64-bit Windows PC for which I cannot obtain a wireless NIC.
Can someone explain, in general, (1) the iptables rules to be set on the eee which are required to share Internet connection with the router, and (2) the router settings required to use the eee as the WAN connection?
Note: IP of the eee is 192.168.1.x and the router is assigning subnet of 192.168.x.x, so I need instructions on how to ensure there are no IP 'collisions'.
