Issue with NFS over NAT since kernel 3.8.x

[leroy christophe]

I have a system with a panel PC running RedHat 7.3, mounting NFS from a
RedHat 9 NFS Server.

Inbetween, I have a router which is running standard Kernel 3.8.13 and
provides NAT (Masquerade) to the PC.

Reading the directory and a first file from the PC works well. But when
trying to read a second file, the router stops forwarding the packets
from the server back to the masqueraded PC.

It was working well with Kernel 3.7.10
It still fails with Kernel 3.10

Is there any change between 3.7 and 3.8 which could explain it ? How can
I investigate this problem ?

You do a git-bisect to find the exact change.
