Hi Machael,

Let me setup another packet capture at each side to see if the initial
packets are being modified at all.

Thanks,

Hi Tony. No firewall in the way.

Physical flow is as below.

Server A -> Nexus 7k -> 3845 router -> Sprint MPLS -> 3845 router ->
Cisco
3750x stack -> Server B

I blame the cloud.

Dump the actual packets as they leave Server A and arrive at Server B
(and vice-versa!). Does it get modified en route?
