Bridging again

[Gergo Szakal]

Followed the advice here:
http://leaf.dragonflybsd.org/mailarchive/users/2006-05/msg00148.html
and tried to pass thru the traffic of the whole dormitory but it does 
not seem to pass packets (even with PF disabled). With OpenBSD 3.8, I 
have done the same (/etc/bridgename.bridge0 and same PF configfile) and 
it works fine, bu I would like to run DragonFly. :-)
Can somebody recommend diagnostic steps or give me some hints?
Thanks, and sorry for bothering. ;-)
