Chapter 6 Configuring Advanced Settings

Advanced Port Forwarding

Selecting Advanced Port Forwarding in the Advanced Setup tab generates the

“Advanced Port Forwarding” screen. Port forwarding allows certain programs

to bypass the Modem’s built-in firewall, allowing access to parts of the network

(for hosting a Web or ftp server, for example). To use port forwarding, enter the

IP port range in the “IP Port Range” text boxes. (If more than 10 ports are needed,

Actiontec recommends using DMZ Hosting. See “DMZ Hosting” on the next page

for more information.) Choose the protocol type from the “Protocol” list box, then

enter the IP address of the computer on the network to be used as a host. Click

Add. The forwarded ports appear in the “List of Forwarded Ports” text box.

To remove forwarded ports, highlight them, then click Remove.

In this screen, the user can also allow only certain IP addresses to access for-

warded ports. Enter the port range of the forwarded ports in the “Remote IP Port

Range” text boxes, enter the IP address to be allowed access in the “Remote

IP Address” text box, then click Add. The active forwarded ports will appear in the

“List of Forwarded Ports” text box.

To deactivate a forwarded port, select it from the “List of Forwarded Ports” text

box, then click Remove.
