With my connection, I noticed that the circuit would disconnect and reconnect periodically. It corresponded to the timeout in my firewall causing the UDP association to be lost. When I increased the timeout in my firewall for these port 700 UDP "connections", that made my circuit much more stable. Unfortunately, my firewall (a SonicWALL NSA 240) is also stupid in that it *must* randomize the source port for outgoing packets, so I'm not able to connect to HECnet because MultiNet insists that the source port must also be 700 and mine are coming through with random port numbers. --Marc IP and UDP is connection-less.. -:) Throw the firewall away. Find a real router that can do DECnet routing and NAT and Firewall somwhere. .. We had this discussion at DCL, and Bob A has a home gw (forgot what it was) that he claims do the right thing, (not decnet routing..) -P
