It's not actually a DSL router, but just a DSL modem capable of being hooked to ethernet directly. My current hub only has 4 ports, and all 4 are in use before the modem arrived. The modem does indeed to nat and uses PPPoA encapsulation for it's VPN portion from my system to MSN via qwest.

The modem does a DHCP for the ethernet card it is connected to, assigning it 192.168.1.2 Should I permanently assign that address to the eth0 interface or leave it as DHCP assigned? >> 2.
