Um, you are HORRIBLY confused. Of course you can forward UDP through a
NAT.  Otherwise not even DNS would work!  There are two main issues
with UDP through NAT:

	1) protocols that include source/dest port numbers _within_
           the protocol (ala Kerberos/Zephyr/etc.) will fail.

	2) protocols that require server callbacks (ala AFS) require
           you to increase the NAT timeout.

But besides that, there is no reason UDP cannot flow through NAT (I do
it almost every day!)

This I agree with whole-heartedly.  I'd really suggest you look into
more secure network file systems.  Take a look at www.openafs.org!
