Hi,

I don't want to bridge, I only said I have to when using ebtables. I need MAC 
filtering without bridging... I'm fully aware of the fact that iptables works 
on layer 3 and that MAC is layer 2, however if it can filter on source MAC 
addresses, why can't it filter on destination MAC addresses?

Best regards,
Erwin
