When I installed the 4.0.3 O.S. I set the addresses and data "by the book". Now, when the second enet controller (ie1) is off (not turned on by the rc.local currently) the primary net works fine. When I turn on the gateway net card (ifconfig ie1 ego-gw -trailers up) the local net stops and the other net is reachable. Perhaps I don't understand the use of the netmasks and relationships to yellow pages correctly. Could any successful gateways implemeentors please suggest hints? Thanks Gary Trimble
