Comment 4 for bug 1510475

A few questions:

What type of interfaces are port1, port2 and port3? Are these actual physical NICS? I see that speed and duplex values are invalid. I also see from the output you have given that the statistics are all 0.

Please run tcpdump on these interfaces to see what kind of packets are ingressing and egressing and let us know your observations

In the successful case, are you sure that you haven't connected your physical device to 'veth_wan' interface?

Thanks
