Hi - I'm using kernel 2.4.18 with netfilter 1.2.7a, and I'm having a problem. I'm writing some code to map MAC addresses to IP addresses using the QUEUE target and ipq_get_packet(), since our bridge code doesn't put the entries into the arp table. I'm seeing the MAC addresses correctly of most of the nodes on our network, however, several machines are reporting an IP address of 00:00:00:00:00:00. Ethereal, when running on a different machine, shows the correct address. Any thoughts? TIA, Paul
