6 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.

This broadband router supports four types of NAT functions, and the instructions of these

functions will be given below.

1 Virtual Server

This function allows you to redirect a port on Internet IP address (on WAN port) to a

specified port of an IP address on local network, so you can setup an Internet service on the

computer on local network, without exposing it on Internet directly. You can also build

many sets of port redirection, to provide many different Internet services on different local

computers via a single Internet IP address.
