We have NFS partition that are accessed across multiple routers with out
any problems.  One thing we did end up doing was to reduce the read and
write sizes to 1K for these partitions.  Otherwise there is a high
probability the gateway will have to fragment the request.  Not too sure
about how to enable UDP checksumming.  Seem to remember that there is a
variable one needs to change with adb to make it happen.  I would need to
go look at the sources.
