5.2.6 NAT
All computers must be assigned with a public IP address to get connected to the Internet without NAT.
However, Internet Service Providers only provide very few IP addresses to every user. Therefore it is
necessary to use NAT to share a single public IP address to multiple computers on local network, so
everyone can get connected to the Internet.
Please choose Enable or Disable the NAT function.

5.2.6.1. Port Forwarding
This function allows you to redirect a single port or consecutive ports of public IP address to the same
port range of the IP address in 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 numbers of Internet IP address
and private IP address are different, please use Virtual Server function, described in next section.
