Subject2.4.0t8: hard reboot with iptables/ipmasq
[reposted under __corrected__ subject line]

My linux box was set up for ipmasq with:

modprobe iptable_nat
iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward

a windows box had been browsing the net through the linux box several
hours earlier (about 4 hours), and then left alone. when i went back
to the windows box and tried to browse again from the same IExplorer
window, _SNAP_ and the linux machine just plain up and rebooted

i am __guessing__ the problem had something to do with using an old
IExplorer session so long after it had last been used??? something
about NAT timeouts or something???

but a hard reboot???

apart from this crash, ipmasq had been working fine (just never tested
with that kind of delay time).

other tidbits:

a few hours prior to crash, i got these from net browsing on a
connected windows box:

Sep 24 22:14:34 localhost kernel: NAT: 0 dropping untracked packet c1afb180 1 ->
Sep 25 00:03:12 localhost kernel: NAT: 0 dropping untracked packet c33da540 1 -> 24.191.22.

auth.log marks the last moment of conciousnes:

Sep 25 01:37:01 localhost PAM_unix[19174]: (cron) session closed for user root

no other significants things written to log.
