5.6  NAPT 
Network Address Translation (NAT) hides internal IP addresses of a network from the outside 
world and provides access to the Internet for multiple machines using a single or fixed number of 
public IP addresses. The NAT framework supports both dynamic and static NAT.  
The NAPT-relevant commands are put in the qosc directory. These commands are used to set up 
the NAT. Among the commands, the natif command enables dynamic NAT processing. The 
addressmap and portmap support NAT features.
