translate to a known local PC.
A DMZ is used by a company that wants to host its
own Internet services without sacrificing unauthorized
access to its private network. DMZ allows one IP
address to be unprotected while others remain
protected. The DMZ is located between the Internet
and an internal network’s line of defense that is a

Field Name
Description
DHCP Server
Allows you to enable or disable the DHCP server
Starting Local Address
The starting address used by the built-in DHCP
server to distribute Private LAN IP addresses. In
the example shown, addresses between 2 and 9
can be used for devices on your Private LAN that
require fixed IP addresses such as printers or a
device assigned as a DMZ host
The LAN IP address ending in 1 is reserved
for the internal gateway server. The LAN IP
address ending in 255 is also reserved and
should not be used for CPE devices
Number of CPEs
Enter the maximum number of devices allowed to
connect to the Private LAN.
The maximum number of devices is 255.
This is the combined total of addresses reserved
for static IP addresses, for example, the sum of
the IP addresses between 1 and the value
entered in the Starting Local Address field and
the value entered in the Number of CPEs field.
Note: The sum of the value entered in the
Starting Local Address field and the value
entered in the Number of CPEs field must always
be 255 or less.

How Do I Configure the Gateway Cable Modems?
Reserving IP Addresses
Use the Setup Basic Settings – Fixed CPE IP Assignment page to reserve IP
addresses to be issued by the DHCP server in the gateway to specific devices on
the LAN. This feature allows you to assign a fixed IP address to any device in
your network and eliminates the need to set static IP addresses in your PC or
other network device.
Reserving IP addresses is useful in making sure that a particular PC or other
network device (for example, a printer) is always issued the same IP address.
Another example: when using DMZ Host, the IP address for the DMZ Host will
always be issued to the same PC or device.
If you are not familiar with the Fixed CPE IP Assignment procedures
detailed in this section, contact your cable service provider before you attempt to
change any of the gateway cable modem default Fixed CPE IP Assignment

How Do I Configure the Gateway Cable Modems?
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 gateway cable modem detects outgoing data on a specific IP port number set
in the “Trigger Range,” the resulting ports set in the “Target Range” will open 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 erroneously left open by the router administrator. Therefore,
these ports are not exposed and vulnerable for potential hackers to discover.
If you are not familiar with the advanced settings detailed in this section,
contact your cable service provider before you attempt to change any of the
gateway cable modem default advanced port triggers settings.
Click Port Triggers in the Advanced Settings section of the Setup page to

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,” and 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.
If you are not familiar with the advanced settings detailed in this section,
contact your cable service provider before you attempt to change any of the
gateway cable modem default advanced DMZ host settings.
Click DMZ Host in the Advanced Settings section of the Setup page to access
the Setup Advanced Settings – DMZ Host page.
Setup Advanced Settings – DMZ Host Page Example

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.

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.
Follow these steps to use either the Keyword or Domain Blocking feature.
1. Select Enable on the Setup Firewall - Web Filters page for the feature or
features you want to use, then click Apply to activate the feature.
2. Enter the Domain Name, Keyword, text string, or URL to which you wish to
restrict access into either the Keyword List or the Domain List field.
The entries must be an exact match in order to be filtered or blocked.
3. Click either Add Keyword or Add Domain as necessary to add the entry to
the list.
4. Repeat steps 1 through 3 for each Domain or Keyword you wish to enter.
Once entered, each new entry will immediately be blocked for all users not listed
in the “Trusted Computers” field in the lower portion of the Setup Firewall – Web
Filters page.
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.
Trusted Computers
Use the Trusted Computers field to specify the MAC address of computers
whose content will always be trusted and allowed unrestricted access to the
Internet.

Description
Authentication
When encryption is enabled, this selection allows
you to choose one of the following authentication
methods from the drop-down list:
• Open System—Open system authentication
allows any device to authenticate and then
attempt to communicate with the WAP.
Communication occurs if both devices have
matching pre-configured WEP keys. Open
System authentication does not provide the
client with confirmation that the link has been
established. This makes it more difficult for a
hacker to access the network.
• Shared Key—During shared key authentication,
the WAP sends an unencrypted challenge text
string to any device attempting to communicate
with the WAP. The device requesting
authentication encrypts the challenge text and
sends it back to the WAP. If the challenge text is
encrypted correctly, the access point allows the
requesting device to authenticate. Shared key
authentication provides the client with feedback
when a link is denied where Open System
authentication does not.
• Open System or Shared Key—Either Open
System or Shared Key can associate with the
WAP and the WAP accepts data from wireless
clients using the appropriate form of
authentication.
Closed Network
Allows you to disable or enable the network to
access by wireless clients. When ON is selected, the
access point does not broadcast the SSID. The
client device must be configured manually with the
SSID and the MAC address of the access point in
order to access with wireless network.
Allow/Restrict
Access
Enables unrestricted access or limits access to
clients listed in the Access List
Access List
Displays the MAC address of the clients that are
allowed to access the wireless access point
Connected Clients
Displays the Host Name, IP Address, and Client ID
of wireless clients that are connected to (associated
with) the gateway modem

Wireless – Advanced page.
If you make changes in the Setup Wireless – Advanced page, click Apply
to apply and save your wireless advanced settings.
Field Name
Description
Basic Data Rates
Displays the default initial data rate for associating with
a WAP. For maximum client compatibility, it is
recommended that the Basic Data Rates are set at
1, 2 Mbps so that older cards can easily gain access to
the network. This setting specifies the minimal set of
required data rates
Control Tx Rates
Displays the transmit data rates the WAP uses is a
function of signal strength and signal quality. For
maximum potential link speed, it is recommended that
you select all control Tx rates: 1, 2 Mbps, 5.5 Mpbs,
and 11 Mbps
Beacon Interval
Displays the time interval that the WAP uses to
announce itself to remote devices. The Beacon
Interval should be left at 100ms for compliance with
most client cards. The Beacon Interval specifies how
often packets are sent by the Access Point (AP) to
synchronize a wireless network and it’s clients
DTIM Interval
Displays the time interval between
Broadcasts/Multicast transmissions. The DTIM
(Delivery Traffic Indication Message) Interval is a
countdown informing the wireless clients of the next
window for listening to broadcast and multicast
messages. When the AP has buffered broadcast or
multicast messages for associated clients, it sends the
next DTIM with a DTIM Interval value. AP clients hear
the beacons and awaken to receive the broadcast and
multicast messages. The DTIM Interval should be left
at 3 ms for compliance with most client cards
Fragmentation
Threshold
Fragmentation and ready to send (RTS) thresholds
should be set equivalent to the maximum Ethernet
frame size allowable on the link including overhead
(1536 bytes). Lesser settings can damage data
throughput as large frames could be fragmented or
collisions could occur
RTS Threshold
The RTS/CTS threshold determines at what packet
size beyond which the RTS/CTS mechanism is
invoked.
