Hello all,
My OpenBSD firewall is still randomly stopping routing packets and I
still can't figure out why. :-(
I made the suggested patch to if_ether.c, ut now I just get the
following line in /var log messages:
Feb 14 18:08:41 bytor /bsd: arpresolve: can't allocate llinfo for
192.168.1.1:no link address
Symptoms: Firewall can ping the wifi router (to which ADSL modem is
attached), but pinging anything beyond it fails. If I try to traceroute
to some place beyond the router, it doesn't show the router as the first
hop. (If it can ping the router, shouldn't it show up a the first hop on
a traceroute?). Even though the firewall can ping the router, it cannot
ping my laptop, even though the route to both goes out ral0. The laptop
cannot ping the firewall either. I know the router is still working
because my laptop can still access the internet through it once I reset
the default gateway to the router instead of the firewall. IPv6 ssh
connections form the laptop to the firewall stay active.
Things is, "arp -a" and "route -n show -inet" show extactly the same
thing whether the problem is currently in progress or everything is
working perfectly. No NICs accidentally have addresses on the wrong segment.
I had routed running, but stopping it has made no difference.
Anybody have any ideas?
