I tried with the WAN on ppp0 instead of wlan0 and it worked! The only iffy thing is I manually specify the eth0 gateway IP to match the gateway IP for ppp0 which was DHCPed by wvdial. Is there a way to make that more dynamic so I don't have to match the eth0 gateway IP and the DHCPed ppp0 gateway IP? Here are my configs: laptop1 eth0 (managed by wicd) IP: 192.168.0.1 Netmask: 255.255.255.0 Gateway: the.ppp0.gateway.ip DNS: the.ppp0.gateway.ip router/AP device IP: 192.168.0.30 Netmask: 255.255.255.0 Gateway: 192.168.0.1 laptop2 wlan0 (managed by wicd) IP: 192.168.0.31 Netmask: 255.255.255.0 Gateway: 192.168.0.1 DNS: 192.168.0.1 As Dan mentioned in the previous thread, should I be able to use a wireless network interface instead of the router/AP device? - Grant
