freebsd security - Apr 2004 - ipfilter/ipfw + bridge + out checking

Hi all.

I didn't find any thread discussing it, sorry if I am re-posting the same
subject.
Is there a way to check the ipfilter/ipfw out-flow with bridge? Is it
implemented?

I've heard its not done due a performance issue (it's writen in
ipf-howto),
but performance is not the main goal for me in this single situation. I
would like to have the stateful firewall and the bridge _fully_ working
together.

Best regards,
