3-6 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.
3-6-1 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.
