See other comments inline below. Tried tcpdump on bering via the cmd tcpdump -i eth0 icmp -q
I get no output for several pings from the internal machine to both successful and unsuccessful (e.g. a router beyond the lab gw, which I can ping from the lab gw, but not from bering or the internal host). Thought with -q I would get output but apparently not. Upon ctrl-C tcpdump says xx packets received by filter 0 packets dropped by kernel. That seems to absolve bering unless there is something I haven't thought of.

Just not beyond.--R. - do you have the cisco as default gateway Yes, on bering external IF.--R. cheers Erich ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
