Thank you.  This information is good to know since I recompiled parts of 
Packet Firewall and then rebooted the machine with no working Packet 
Filter as a result.

I have adjusted to the changes and am running OpenBSD 5.1 on my perimeter. 
Also, I am experimenting with NPF on NetBSD, which has a few bugs but 
generally works just fine tested with 'nmap' and the like.  For FreeBSD, I 
will change to IPFW.  It might be useful anyhow, since I have a Macintosh 
and will eventually probably get another.  I would guess that the 
Macintosh firewall is still 'ipfw2', or something not too dissimilar.

There is just no sense banging my head against a wall and repearting 
mistakes that actually do not belong to me by trying to run Packet Filter 
on FreeBSD.
