Chapter 6 Advanced Setup
Port Forwarding
Selecting Port Forwarding in the “Advanced Settings” screen generates the “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.
Clicking Advanced brings up the “Advanced Port Forward” screen.
In this screen, the user can allow only certain IP addresses to access forwarded
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.”
