I'm guessing the subnet on both is 192.168.2/24. Correct. Netmask is /24. > > Unless things have changed since the last time I looked into this, for IPv4 Linux implements what's referred to as the "weak" address binding model where IP addresses are considered to belong to the host not the interface. That means your host may be transmitting an ARP response, but not out the interface you expect, particularly if in fact you have the same subnet assigned to more than one interface. > > You might want to tcpdump on all interfaces when you do this. I actually did that (after some googling) but there's no ARP response being transmitted out of either of the interfaces. As I mentioned before, this problem happens even with regular ethernet interfaces and not specifically with my custom hardware related ones, so looks like a routing (mis)configuration issue. > > Also, you might want to include the output of the following in future posts: > > ip addr show > ip route show > ip neigh show I'll now test with 2 "regular" ethernet interfaces on my test machine (eth0,eth1) and send the o/p of these commands.
