Multiple Interfaces on Same Ethernet Broadcast Network ------------------------------------------------------ Due to the default ARP behavior on Linux, it is not possible to have one system on two IP networks in the same Ethernet broadcast domain (non-partitioned switch) behave as expected. All Ethernet interfaces will respond to IP traffic for any IP address assigned to the system. This results in unbalanced receive traffic. If you have multiple interfaces in a server, either turn on ARP filtering by (1) entering: echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter (this only works if your kernel's version is higher than 2.4.5), or (2) installing the interfaces in separate broadcast domains (either in different switches or in a switch partitioned to VLANs).
