How Do I Configure the Cable Modem Gateway?

Setup Advanced Settings - Port Forwarding Page Description

The following example illustrates how to use the port forwarding feature to configure the Microsoft X-Box Online Live for Internet gaming.

Note: For most widely used applications (including Microsoft X-Box Online Live), the built-in firewall automatically maps and opens ports required for that application while the application is in use.

Set the device to be used for port forward to a fixed IP address, for

example, 192.168.0.5.

In the first entry of the Port Forwarding area of the page, enter the

2. same IP address (192.168.0.5) in the Local IP Address field.

In the same row, enter the appropriate port numbers in the Start

3. Port and End Port fields.

In the same row, select the appropriate protocol from the drop-

4. down list in the Protocol field, and then select the box in the Enable field.

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.

Click Port Triggers in the Advanced Settings section of the Setup page to access the Setup Advanced Settings - Port Triggers page.

Setup Advanced Settings - DMZ Host Page Example

The following illustration is an example of the Setup Advanced Settings - DMZ Host page.

Setup Advanced Settings - DMZ Host Page Description

Use this page to place a Private LAN IP device; for example, an FTP, Mail, or Web server directly on the Internet (bypassing the firewall). You set the server with a fixed IP address as a DMZ Host by entering its IP address in the DMZ Address field. Make sure the IP address used is not in the range of addresses delivered by the builtin DHCP server. After setting up a DMZ Host, all ports on this device are open to the Internet. You may configure only one PC to be the DMZ host. DMZ is generally used for PCs running “problem” applications that use random port numbers and do not function correctly with the specific port triggers or port forwarding setups described earlier in this guide. After entering a DMZ Address, click Apply to apply and save your new DMZ Host setting.

Setup Parental Control - Basic Setup Page Description

This section describes the section headings and fields descriptions of the Setup Parental Control - Basic Setup page. This page allows you to create Internet access rules based on the content found in the URLs of Internet sites.

Field Name Description

Rule Configuration Allows you to add a new content rule. Enter the name

of the rule and click the Add Rule button to add the content rule to the list. Content rules are used to restrict Internet access based on IP addresses, domains, and keywords found in the URLs of Internet sites.

Note: It may be useful to set up your first rule as “No Rule,” without any restrictions or settings. This setting will allow you to assign “No Rule” status to users who are not subject to “content-related” access restrictions.

Rule Settings Allows you to edit a content rule by using the drop-

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.

Keyword List Allows you to create a list of keywords. Any attempt

to access a URL that contains any of the keywords in this list will be blocked by the gateway.

Blocked Domain List Allows you to create a list of Domains that the

gateway should block access to. Any attempt to access any of the Domains in this list will be blocked by the gateway.

override user access restrictions to a blocked Internet site.

Re-enter Password Re-enter the same password for confirmation of the

override password in the previous field.

Function Keys

Key Description

Add Rule Adds and saves a new Rule to the list of content Rules

Remove Rule Removes the selected rule from the content rule list

Add/Remove Keyword

Add/Remove Domain

Add/Remove Allowed Domain

Apply Saves all additions, edits, and changes

Allows you to add new keywords to the list or to delete selected keywords from the list

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.
