Well, it is more complicated than that. Many people do think that NAT  
boxes are layer 3 devices, and if you have a double-nat mechanism then  
"messing around with DNS packets" is a needed feature. Sure, then one  
start walking from layer 3 towards layer 9.... But...

Anyway, this is not when we should fight about wording. We all know  
what we talk about, and I think we should thank Patrik and others what  
they have done.
