suddenly this occured to my mind that, as you know, each firewall has a
virtual interface on system which they listen to..

so, isn't it possible to just forward required packets from ipfw to pf's
virtual if?

i have to mention that this is just an all-of-a-sudden idea and i'm not
sure about it's being right at all..

may be someone else can give both of us a tip on its being right or wrong??


Best Regards,
