Reserving IP Addresses
Use the Setup Basic Settings - Fixed CPE IP Assignment page to reserve IP
addresses. This feature allows you to assign a fixed IP address to any device in your
network by setting static IP addresses in your PC or other network device.
These addresses will be removed from the pool of the IP addresses to be used by
your gateway's DHCP server when issuing IP addresses to devices that are
connected to your local network.
Reserving IP addresses is useful in making sure that there are no IP address conflicts
on the network, for example, two devices using the same IP address. Another
example: when using DMZ Host, the IP address for the DMZ Host should always
have the same IP address.

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.

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.

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

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.
