Hi,

For technical (and especially customer) reasons, i setted up a firewalling solution based on FreeBSD 4.x (kernel compiled with BRIDGE option) and ipf.

No more particular stuff. You'ld find others configuration details at the end of this post (dmesg and more).

Now, the problem. Randomly, ipf starts to reject incomming connexions that should be ok (as wrote in the rules file).

If i reload ipf, things become nice again.

I really get lost with this ..

Any Help would be appreciated.

Iface are intel cards using fxp or em drivers.
