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 built-
in 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.
