Hi Some days ago, Dan Searle asked for a mac match extension where it should be possible to apply arbitrary masks to the mac address: http://msgs.securepoint.com/cgi-bin/get/netfilter-0210/170.html I extended the mac matching code and attached the patch to this e-mail. Although I think that this feature will be used very rarely it might be helpful to have it in patch-o-matic. Anyway, it's your decision. If you don't like it or believe that it is not useful throw it away ;-) Regards, Thomas
