Hi Jim, Immediately lost or lost after a couple of minutes of no output? If there's a long delay, see path mtu detection in my prior post. If not... If immediate, try it from in front of the sonic wall instead of behind it. If it works, your sonic wall is malfunctioning (maybe Sonic Wall is mad that you're checking out a competitor ;) ). If you get the same result (lose the connection 75% of the way through), dig out wireshark and see what packets you send and receive right around the connection lost. It would help to know whether you're getting a TCP FIN, a TCP RST or a destination unreachable, and if the latter which one and from what IP. Regards, Bill Herrin -- William D.
