If you look in if_bridge.c:bridge_pfil you will see that the ethernet header is stripped from the mbuf before passing to pfil. You may want to create another hook such as ether_pfil_hook and modify the bridge to use it. Alternatively see the recent discussion between Julian and Andre on the matter. cheers, Andrew _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
