Hello, I'm facing a strange behave on the ARP answers from my TQM885D module (U-boot 1.3.0-rc2 and kernel 2.4.25). When I connect both Ethernet interfaces, for example configured as follow:
Eth1: IP 192.168.0.126 MAC 00:23:DE:CC:12:01 Eth2: IP 192.168.11.126 MAC 00:23:DE:CC:12:02 If an ARP request arrives from the net the module sends two answers (from the two interfaces) with the same IP and different MACs. Here the packets I can see on the Ethernet sniffer: Source Destination Protocol Info ------------------------------------------------------------------------------------------------------------------------------------------------ CompaqHp Broadcast ARP Who has 192.168.0.126? 00:23:DE:CC:12:01 CompaqHp ARP 192.168.0.126 is at 00:23:DE:CC:12:01 00:23:DE:CC:12:02 CompaqHp ARP 192.168.0.126 is at 00:23:DE:CC:12:02 Anyone can tell me the reason why I'm getting also the second answer (of course a wrong answer) ?
