hello; i may have found part of the problem. each interface in the laptop router has an unique ip address. i.e. eth0 == x.y.z.202 eth1 == x.y.z.208 eth2 == x.y.z.209 eth3 == x.y.z.210 in rereading the linux wireless howto the example router has the same ip address on all interface. i.e. eth0 == x.y.z.202 netmask 255.255.255.255 eth1 == x.y.z.202 netmask 255.255.255.255 eth2 == x.y.z.202 netmask 255.255.255.255 eth3 == x.y.z.202 netmask 255.255.255.255 with a default route on eth2. i would assume that eth0, eth1, and eth3 are all proxy-arped.
