3-2 Network Address Translation (NAT) 
 
Network address translations solve the problem if sharing a single IP address to 
multiple computers. Without NAT, all computers must be assigned with a valid 
Internet IP address to get connected to Internet, but Internet service providers only 
provide very few IP addresses to every user. Therefore it’s necessary to use NAT 
technology to share a single Internet IP address to multiple computers on local 
network, so everyone can get connected to Internet.   
 
Please follow the following instructions to set NAT parameters:

3-2-2 Port Forwarding 
 
This function allows you to redirect a single port or consecutive ports of Internet IP 
address to the same port of the IP address on local network. The port number(s) of 
Internet IP address and private IP address (the IP address on local network) must 
be the same. If the port number of Internet IP address and private IP address is 
different, please use ‘Virtual Server’ function, described in next section.
