What kind of problems do you see? It can be hard to get firewall

unless you have hundreds of busy clients.
What I mostly see is every imaginable problem on different machines
at different times :-).
I think the root cause is related to having vast numbers of different
versions of unix/linux on different machines all of which claim
to "support" NFS, but which together are highly unreliable (especially
the ones too old to support tcp connections).
The worst problem is data corruption on writes, especially writing
large files across NFS, they will often wind up with large chunks of
zero bytes in place of the actual data.
You don't happen to be writing a given file from 2 different machines do you?
ie odd blocks from one machine, even from the other?
I have not had that bad of luck with NFS, and I have been using in since linux
2.2 against a variety of Unix machines.
