To add additional ports, repeat steps 1 through 4, and then go to
5. step 6.
6. Click Apply to apply and save your new port forwarding settings.

Configuring TCP/UDP Port Triggers

Use the Setup Advanced Settings - Port Triggers page to configure TCP/UDP port triggers. Port triggering is similar to port forwarding but is dynamic. In other words, the system does not hold the ports open indefinitely. For example, when the cable modem gateway detects outgoing data on a specific IP port number set in the “Trigger Range,” the resulting ports set in the “Target Range” opens for incoming data. If the system detects no outgoing traffic on the “Trigger Range” ports for a period of 10 minutes, the “Target Range” ports close. This is a safer method for opening specific ports for special applications, such as video conferencing programs, interactive gaming, and file transfer in chat programs. This is safe because the ports are dynamically triggered and not held open continuously or left open erroneously by the router administrator. Therefore, these ports are not exposed and are not vulnerable for potential hackers to discover.
Note: If you are not familiar with the advanced settings detailed in this section, contact your service provider before you attempt to change any of the cable modem gateway default advanced port triggers settings.
Click Port Triggers in the Advanced Settings section of the Setup page to access the Setup Advanced Settings - Port Triggers page.

Configuring the DMZ Host

Use the Setup Advanced Settings - DMZ Host page to configure an IP address that is visible to the WAN. DMZ hosting is commonly referred to as “exposed host.” DMZ hosting allows you to specify the “default” recipient of WAN traffic that Network Address Translation (NAT) is unable to translate to a known local PC. DMZ allows one IP address to be unprotected while others remain protected.
Note: If you are not familiar with the advanced settings detailed in this section, contact your service provider before you attempt to change any of the cable modem gateway default advanced DMZ host settings.

down menu to recall the rule to be edited.
To remove a user profile, use the drop-down menu to select the rule to be removed and click on the Remove Rule button.

Allows you to add new domains to the list or to delete selected domains from the list
To use keyword and domain blocking
Keyword and Domain blocking allows you to restrict access to Internet sites by blocking access to those sites based on a word or a text string contained in the URLs used to access those Internet sites.
Domain blocking allows you to restrict access to Web sites based on the site's Domain Name. The Domain Name is the portion of the URL that precedes the familiar .COM, .ORG, or .GOV extension.
Keyword blocking allows you to block access to Internet sites based on a Keyword or text string being present anywhere in the URL, not just in the Domain Name.
Note: The Domain blocking feature blocks access to any Domain in the Domain List. It will also block Domains, any portion of which contains an exact match to entries in the list.
For example, if you enter example.com as a Domain, any site that contains “example.com” will be blocked. Generally, you do not want to include “www.” in a Domain Name since doing so limits the blocking to only the site that matches that Domain Name exactly. For instance, if you enter www.example.com into the list, only the one site that matches that name exactly will be blocked. Consequently, if you do not include the “www.,” then all sites within and associated with “example.com” will be blocked.
