How Do I Configure the Cable Modem Gateway?

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.

Configuring Firewall Protection

Use the Setup Firewall - Options page to configure Web page filtering and firewall protection. This page allows you to enable various firewall protection filters.

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 firewall options settings.

Click Options in the Firewall section of the Setup page to access the Setup Firewall - Options page.
