IPF dropping my TCP sessions

[Martti Kuparinen <martti.kuparinen%iki.fi@localhost>]

Hi,

I have big problems with IPF 4.1.29 on NetBSD 5.0_RC2. I had two SSH sessions 
open and they were visible as

Source IP             Destination IP         ST   PR   #pkts    #bytes      ttl
10.0.18.3,36821       xxx.xxx.xxx.130,22    4/4  tcp     213     21388  3:58:26
10.0.18.3,45536       xxx.xxx.xxx.140,22    4/4  tcp      43      7668  3:59:55

Later (say 15 minutes or so, i.e. not even close to the TTL) I noticed both my 
SSH sessions were unresponsive so I logged into the firewall and and saw no 
state entries for my SSH sessions.

Anyone else having similar problems with IPF on NetBSD 5.0?
