Given that NATs violate the internet protocol anyway, once you've decided
to use NATs, any question of validity is moot.  The only 'valid' way to use 
NATs is to turn them off.

NATs break lots of applications, often in mysterious ways.

So if it works for you, great.  If it doesn't - that's to be expected.
