I have a machine doing ipnat, it seems to crash often when it is trying to do 
it's job. It was running 1.2 + ipfil3.1.2 until yesterday, now I upgraded it 
to 1.2-current.

When I do ipnat -l i get the following

myssy# /sbin/ipnat -l
map ep0 10.0.0.0/8  -> 194.111.174.224/255.255.255.240 portmap tcp/udp 
2048:65000
10.1.2.89 1372 <- -> 194.111.174.225 2056 297 2 67a3 [239.190.173.222 61374]
10.1.1.11 137 <- -> 194.111.174.225 2057 1100 2 6dc5 [239.190.173.222 61374]
10.1.2.89 1372 <- -> 194.111.174.225 2056 297 2 67a3 [239.190.173.222 61374]

Notice that 239.190.173.222 (the other-ip, where the connection is open to), 
is 0xDeadbeef. (dunno if it's the ipnat(8) or kernel that has it wrong).

The crash message is:
myssy% /sbin/dmesg -M netbsd.1.core -N netbsd.1 | tail -4
fatal page fault in supervisor mode

myssy% uname -a
NetBSD myssy 1.2B NetBSD 1.2B (FIRE) #1: Thu Jan 16 03:07:15 EET 1997

Any ideas ?
