Introduction
The CBW500 Wireless Cable Residential Gateway is a broadband gateway
product combining Ethernet network and wireless together. With IEEE 802.11g
standard wireless integration, this device not only allows you to take an
advantage of wired-free data transmission, but also allows you to have 4 of
10/100 Mbps Ethernet connections with auto-sensing switch Ethernet ports.
This combination of router and switch product eliminates the needs to buy an
additional hub or switch to serve your network, so users on either WLAN
(wireless LAN) or wired LAN can share files, other networking resource, and
even for a single account of Internet access by having this device connect to a
Cable modem.
The CBW500 allows up to 253 total (128 wireless) users to share a single
Cable connection. A high-speed routing engine and 54Mbps (802.11g
standard) wireless throughput easily handle large data transmission, including
those from multimedia applications.
802.11g also backward-compatible with 802.11b WLAN equipment, preserving
existing network investments.
The CBW500 can work as DHCP server to assigns an IP Address to every PC
on the LAN automatically and/or work as DHCP client to get an IP address
dynamically assigned by ISP. CBW500 Cable Residential Gateway is easy to
setup and maintain. All functions can be configured via web browsers such as
Internet Explorer.

Getting Started
Web Configuration
You can access the Configuration
Page by opening the web-browser
and typing in the IP Address of the
CBW500. The default IP Address of
the CBW500 is shown as right.
Leave the User name as blank and
the password as cable and then
press OK button. It is recommended
that you change the default
password for security purposes.
Please go to Status > Security to
change your password.

Configuration Menu
7.1 Status
7.1.1 Software
This page displays information of current system software.
4

7.1.2 Connection
This page displays information of status of cable modem’s HCF and IP
network connectivity.
5

7.1.3 Security
This page allows configuration of administration access privileges and the
ability to restore system’s factory defaults.
Administrator can change the logging password in this page. It is
recommended that you change the password once you have accessed the
CBW500 for the first time. The password can be up to 64 characters.
This page also provides an easy way to restore the factory defaults settings if
you want to clean all the existing settings or reset your settings.
6

7.1.4 Diagnostics
This page provides ping diagnostics function to help user solve IP connectivity
problems.
PING is a utility, which is used to determine whether a device is active at the
specified IP address. PING is normally used to test the physical connection
between two devices, to ensure that everything is working correctly.
Enter the settings of Ping target and then press Start Test to start the
diagnostic. The results will display in Results table and you need to refresh this
web page to update the diagnostic results.
7

7.2 Basic
7.2.1 Setup
This page allows configuration of the basic features of the broadband gateway
related to your ISP’s connection.
There are three options of obtaining a WAN IP address.
1. Obtain WAN IP Address by DHCP
2. Static WAN IP Address (for most leased line users)
3. Obtain WAN IP Address by PPPoE (for most dial-up users)
Select the item according to your situation and enter the information required
by your ISP. Press Apply to confirm the settings.

7.2.2 DHCP
This page allows configuration of DHCP server for LAN.
You need to enable (default) DHCP server feature and indicate the Starting
Local Address for the DHCP server to start with when issuing IP addresses
and the number of CPEs (clients).
Starting Local Address Because the CBW500’s default IP address is
192.168.0.1.the Starting Local address must be 192.168.0.2 or greater, but
smaller than 192.168.0.253. The default Starting Local Address is
192.168.0.10.
Number of CPEs Enter the maximum number of PCs that you want the DHCP
server to assign IP addresses to. This number can not be greater than 253 and
the default is 245.
9

The DHCP Client Lease Info table displays the PCs that are given IP
addresses by the CBW500. For each PC, the list shows the MAC Address, IP
Address, Subnet Mask, Duration and Expires.
7.3 Advanced
7.3.1 Options
This page allows configuration of advanced features of the CBW500.
WAN Blocking By enabling the Block WAN feature, you can prevent your
network from being pinged or detected by other Internet users.
This feature also reinforces your network security by hiding your network ports.
Both functions of the Block WAN Request feature make it more difficult for
outside users to work their way into your network.
IPsec PassThrough IPsec (Internet Protocol Security) is a suite of protocols
used to implement secure exchange of packets at the IP layer. To allow IPSec
tunnels to pass through the CBW500, IPsec PassThrough is enabled by
default.
10

PPTP PassThrough PPTP (Point to Point Tunneling Protocol) is the method
used to enable VPN* sessions to a Windows NT4.0, 2000 server. To allow
tunnels to pass through the CBW500. The default setting is enable.
*VPN (Virtual Private Networking) is a security measure that basically creates
a secure connection between two remote locations.
Remote Config Management This feature allows you to manage your
Gateway from a remote location, via the Internet. To enable this feature, tick
Enable, and use the specified port (default is 8080) on your PC to remotely
manage the CBW500. You must also change the CBW500's default password
if you haven’t already. A unique password will increase security.
To remotely manage the Router, enter http://xxx.xxx.xxx.xxx:8080 (the x’s
represent the CBW500's Internet IP address, and 8080 represents the
specified port) in your web browser’s Address field. You will be asked for the
CBW500’s password. After successfully entering the password, you will be
able to access the Gateway’s web-based utility.
Multicast Enable IP Multicasting occurs when a single data transmission is
sent to multiple recipients at the same time. With Multicast feature enable, the
CBW500 allows IP multicast packets to be forwarded to the appropriate
computers.

7.3.2 IP Filtering
This page allows configuration of IP address filters in order to block Internet
traffic to specific network on the LAN.
Tick Enable check box and enter the IP address or IP address range you want
to block and then click Apply button.

7.3.5 Forwarding
This allows for incoming requests on specific port numbers to reach web, FTP
server and mail servers, etc. so they can be accessed from the public Internet.
The table on the right is commonly used port numbers.
Tick Enable check box and enter the Local IP address, port or port range you
want to block. Select Protocol type and then click Apply button.
