There is no problem, as long you control the NAT router. 

There is a problem if your ISP is forcing NAT on you as
a tool to prevent you from offering services (which technically
means, that your machine can be contacted from the internet).

There may be several reasons for your ISP to do so:

Diffenciated services: You want a machine, that can be contacted from
the internet: No problem, upgrade to a more expensive ISP contract.

Fighting peer to peer: Peer to peer technologies make it very hard to control
 information flow.  So Government naturally do not like peer 2 peer as
 does the content industry. 

John Walker was pessimistic, so he stopped his work with speak freely.
In a very clean way I want to say, everything neatly archived, and a 
clear timetable.
