Thanks a lot for this tip. I am googling for how to fix this. I will add
this now.

I viewed ifconfig -all this morning  and there were no error reported.
if0 is the main network interface that connects to the Internet.
if1 is the network card for internal workstation
if2 is the network card for backup, it connects to the Internet thru an ISDN
line.

the gateway is for the router on if0.

This configuration has worked for about 8 months, then suddenly 3 weeks ago,
and then this morning, that problem occurred.

It *temporarily fixed it by restarting the server.

Thanks,

Vu
