Well I'm not sure about the 'easier' part. I would have thought that it is easier to run something like: echo "1" > /proc/sys/net/ipv4/ip_forward iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE iptables -A FORWARD -i eth1 -j ACCEPT (This needs checking because it's just off the top of my head.) You'll need two NICs, or one NIC and a wireless adaptor on your 'router PC'. However, it is not convenient to always have to boot your first PC up, before any other machines in the house can connect to the Internet. So an external switch/router is probably the most convenient solution. > > The second option is to buy another router.

Unless the 2210 has crippled firmware by the ISP, it should be able to act as a transparent (fully bridged) modem. All NAT-ing, DHCP, DNS repeating, etc will then happen at the router behind it. I doubt that the ISP will not allow it, however, their support staff will undoubtedly go through their MSWindows specific troubleshooting scripts first and after they ask you to reboot your (MSWindows) PC they will probably tell you that they do not support the 2210 in bridged mode and ask you to switch it in router mode so that they can access it remotely. -- Regards, Mick
