No. Ppp won't see the incoming packets and therefore won't be able to do anything with them :-I Natd is the right way to go. I would have thought it works - what does your setup look like ? Are you using ``ipfw ... divert ...'' on both interfaces, diverting both to the same natd, and have you got the same IP number assigned to both interfaces ? The problem here as I see it is not if natd will work, but if the machine will be able to handle things properly. I would have thought the show-stopper would happen when the machine tried to create a temporary route to the target machine based on the interface that an incoming packet from that machine arrived on.... > H -- Brian , , Don't _EVER_ lose your sense of humour....
