 Ivan,
 
 First of all, do you realize that IPFIREWALL and IPFILTER are alternative
 packet filter facilities?
 
 Second, would you mind following the FreeBSD Developers Handbook
 instructions on how to inspect kernel crashes with ``gdb'':
 
 http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneld
 ebug.html
 
 and sending a post-mortem kernel stack trace?  Without it, it's rather hard
 to guess a sequence of calls that leads to the particular crash.  Thank you.
 
 --Yar
