But you can reach dugite from possum ? (I guess yes).
Maybe a silly question but is ip forwarding enabled on possum ?

So every part of the net works for itself but the packets from bobtail
don't reach dugite ?
I guess it's an routing issue (verify that a packet to dugite from bobtail
arrives @possum). Also verify that possum tries to send the packet out to
dugite (arp request, packet itself).

The thing you ar looking for is proxyarp (and your example tells me that
you have found this allready).

Yes, right (dialin/dialout is mostly the same).

Hope it helps,
