Address Translation With NAPT

Many applications require special port access to the Internet in order to function. By enabling Network Address Port Translation (NAPT), multiple computers in your home network have access to the Internet by translating port addresses to an Internet IP address while masking their IP addresses from outside users. Only TCP, UDP, and ICMP protocols support NAPT.

To enable and configure NAPT address translation:

1.Select Port By-Pass (NAPT) from the “Address Translation (NAT/NAPT)” window.

2.Click the Configure hyperlink next to Port By-Pass (NAPT). This displays the “Port-By-Pass Configuration” window.

3.To enable an application for NAPT, click the desired application from the Available Applications list. The application is moved to the Enabled Applications list.

4.Optionally, click the Add a custom bypass entry hyperlink. This displays the advanced features on the Port By-Pass Configuration” window. The advanced option allows you to configure special port access to the Internet.
