Interface can see ARP packets but can't see the ICMP echo requests

Question

Moring SuperUsers, got my self into a pickle.

I have to servers, os-net and vmhost3, connected together via a cross-over cable on their respective 10Gbps interfaces. Both servers are running Ubuntu 14.04 LTS, the only difference is that os-net is virtualized on ESXi. The VM has it's own VMKernel port attaching it to the 10Gbps interface on the ESXi server.

The problem I am having is trying to get the two servers to communicate to each other, if I ping os-net via vmhost3 (ping -c 4 10.0.0.2) it sends the ARP request and gets a response but when it sends the ICMP echo request it gets no reply.

Here is a capture from wire shark on os-net (tshark -i eth0)

If I try the reverse and try and ping vmhost3 from os-net I get this capture (tshark -i em2)
