The ipf source is as I understand it compiled as kernel modules or into 
the kernel and some administrative applications are compiled to interact 
with the kernel.

Hence, as mentioned by Giorgos, upgrading by downloading the source from 
the official site should be done with care. The recommended way is as 
Giorgos say to update your source and go with the current version 
included in FreeBSD.

When I suggested to look at more resent versions it was more to check 
the history and see if there was some bug discovered in 4.1.8 that had 
been corrected and could have been causing your troubles.

If there are such bugs you should file a problem report. If changes are 
minor it may be possible to merge the newer version into the FreeBSD 
code, but at the cost that on next cvsup you will have to do it again 
unless the newer version has been adopted.

If there are no such problems, don't bother to update. In such a crucial 
part of the system it is important to be aware of the actual benefit 
from upgrading.

Cheers, Erik
