Basically, Network Address Translation (NAT) allows a network router, to translate IP address of a public network (the Internet) to IP of a private network (LAN) .This means that only a single unique IP address is required to represent an entire group of computers to anything outside Local Area Network.

The following terms are used when discussing NAT:

  • Inside local address - Usually not an IP address assigned by a service provider and is most likely a private address. 
  • Inside global address -Valid Public IP address that the inside host is assigned to when it exits the NAT configured router.
  • Outside global address - Valid public IP address assigned to a host on the Internet.
  • Outside local address - The local IP address assigned to a host on the outside network. In most situations, this address will be identical to the outside global address of that outside device.
