Hi all,

Have 2.6 OBSD system running as firewall for two years now, using two
vanilla ISA bus NE2000 NICs.  Last few weeks i occasionally lose the
connection from clients on LAN to Internet, while firewall connectivity
to Internet is fine.  When connection is lost to firewall i cannot ping
or ssh from clients on LAN to firewall, yet when i ping from firewall to
clients, the NIC clears and connection is reestablished.

The /var/log/messages log shows "/bsd: ne1: device timeout".  Has anyone
seen this before and if so, does it look like the NIC hardware is
starting to fail ??

I've been getting the same behaviour with 2.7. This has only happened since
Rogers switched to their new dhcp system, so I am running the most recent
dhclient instead of the default one. The solution I have found is to run a
cron job every ten minutes that deletes the routes that have been added to
each individual local machine. The default route for the interface is okay.
after I set up this cron job, there have been no problems.
Originally I set up the cron job to maintain continuous pings to each local
machine, but the connectivity still dropped. The route thing works. I have
no idea WHY it works, though.
