I think there are some NAT routers that will actually accept the outside address when sent to the inside interface which avoids the need for any special consideration since the inside hosts can then send to the right place with the address supplied by public DNS. I don't know which versions do it, though. -- Les Mikesell lesmikesell@xxxxxxxxx
