Also just to reiterate I would lean more heavily on something fishing in the WAN cloud if all traffic from Site 1 to Site 2 were not seeing tcp window scaling properly, however it's only for Server A that is seeing this. Server A is able to properly TCP window scale for any local traffic.

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?
