Another PF question

[Nuno Branco <branco_(_at_)_markdata_(_dot_)_pt>]

I have a big file with rules for pf (about 4000 rules) that are
generated by a script of mine.

What is happening is that when i want to load those rules with pfctl -N
FILE_WITH_NAT_RULES - R FILE_WITH_PF_RULES i momentarily loose network
connection. 

I assume this is while it is enabling the pf rules because with ipf on
OpenBSD 2.9 (and a 3000 rules file) this didn't happen. Is there anyway
i could speed this up?

Is there any option or limitation i didn't see in the pf man file?


Any help would be apreciated.
