I just took a look at your pcap, and yes you are getting no replies from anything outside of your LAN, even a basic DNS query fails to generate any kind of response. It can't be an MTU issue, because that should be handled by your router. However, I did notice that there are quite a few bad packets that needed to be retransmitted - it might be worth doing a similar exercise while connected to the Ethernet switch and see if you get the same number of bad packets and retransmissions.

One thing I notice is that I'm the only one replying in this thread. It might be worth asking for a second opinion on somewhere like Hardforum - there are a few Infiniband users over there. smile.gif
