Address Translation

The Address Translation feature provides different methods of keeping individual users/computers hidden behind a single outward-facing address, while still allowing them to access the Internet and related applications. If you have more than one available Internet connection interface, they will all be displayed in the drop-down menu for ease of selection.

To enable and configure the address translation feature:

1.From the “Security Options” window, select the Address Translation button. This displays the “Address Translation (NAT/NAPT)” window.

2.Select an interface from the Select Interface drop-down menu.

3.Select one of the following options:

•Use no address translation Disables address translation.

•Address Translation (NAT)

Uses NAT for address translation. NAT is an Internet standard that allows a LAN to use one set of IP addresses for internal traffic and a second set for external traffic. This displays the “NAT Address Configuration” window.

•Port By-Pass (NAPT)

Uses NAPT for address translation. Only TCP, UDP, and ICMP protocols support NAPT. NAPT allows many devices connected to the Gateway access to the Internet while masking the identification of the internal IP addresses. This displays the “Port By-Bass Configuration” window.
