Latest data point here: this time it was fixed mysteriously.
After noticing it was down, "netstat -m" showed no serious mbuf
use or peak use. "ep0" had:
ep0: flags=cc43<UP,BROADCAST,RUNNING,OACTIVE,SIMPLEX,LINK2,MULTICAST> mtu 1500
and the IP address was set up correctly
"tcpdump -n -i ep0" worked, and after that the behavior was back to normal.
No restart of natd was done, no firewall rules flushed or reset.
This is on 4.3-STABLE FreeBSD 4.3-STABLE #3: Sun Jul 15 00:27:41 PDT 2001
