Strange. I've got 10GA on one end, and nv21 on the other.
Would those older versions of the OS have anything to do with it?
Maybe not, but I am not sure. Did you try to ping remote side with a
large ICMP payload, like "ping -s <remote> 12000"? And snoop to see if
the MTU you set is the same as real working MTU.
It might help us to know what's the problem.
