Having two separate NICs, with different IP addresses, on the same physical network segment is "tricky" to say the least. You would be better off doing one of two things: - Use only 1 NIC, and assign both IP addresses to it - Bond the 2 NICs and assign both IP addresses to it You could set up routing policy tables, but that's kind of an advanced topic. Otherwise, take a look at the following using the sysctl command: net.ipv4.conf.all.rp_filter net.ipv4.conf.default.rp_filter net.ipv4.conf.lo.rp_filter net.ipv4.conf.eth0.rp_filter net.ipv4.conf.eth1.rp_filter Make sure they're set to 0 and not to 1.
