very curious situation

[vladone]

Hi!
I want to block illegal acces to server with mac address.
For testing i write this rules:

ipfw add 100 deny mac any xx:xx:xx:xx:ab:12 in via $lif
ipfw add 100 deny mac any xx:xx:xx:xx:ab:34 in via $lif

$lif is private interface on my server.

After i apply this rule result is strange. Computer with mac ..ab:12
can make traffic but these with ab:34 no.
I have withe hair.

P.S. computer with traffic is win98 and without traffic is XP.

How he can such something!
