No it cannot. NAT is not possible with some IP protocols. Plain IPSec 
(without NAT-T encapsulation) is the first one that comes in mind.

Also many complex protocols such as FTP or SIP (nothing exotic here) 
require special support and this is not transparent as it requires 
messing with the payload, not only with the packet headers. Use of 
encryption with these protocoles may come in the way and defeat NAT 
handling.
