Chapter 3 Your Gateway At A Glance
The Lynx L-320 has different ports and LEDs. Let’s take a look at the
different options.
3.1 Ports and Buttons
Reset and Restore to Factory Defaults: The restore to factory defaults
feature will set the Lynx L-320 to its factory default configuration by
resetting the Lynx L-320. You may need to place the Lynx L-320 into its
factory defaults if the configuration is changed; you loose the ability to
interface to the Lynx L-320 via the web interface, or following a software
upgrade. To reset the Lynx L-320, simply press the reset button for about ~
10 seconds. The Lynx L-320 will be reset to its factory defaults and after
about 30 ~ 40 seconds the Lynx L-320 will become operational again.
LAN (local area network) ETHERNET port: There are 4 Ethernet ports
available for connection to four Ethernet network devices. If 4 ports are not
enough, you can connect to one of them a hub or a switch.
Power is where you connect the power. Make sure to observe the proper
power requirements. The required power is 9 volts.
DSL Port: This is the WAN interface that connects directly to your phone
line.

Chapter 4 Installing The Lynx L- 320
1. Locate a suitable location for the Lynx L-320. For connections to the
Ethernet and DSL interfaces, please refer to the Quick Guide.
2. Connect the AC Power Adapter. Depending upon the type of network,
you may want to put the power supply on an uninterruptible supply
(UPS).
Note: Please use the power adapter supplied with the Lynx L-320.
A different adapter may damage the product.

Chapter 5 Setting Up the Lynx L-320
The basic tabs consist of features which are catered for basic users.
This section will guide you through your Lynx L-320’s configuration. The Lynx
L-320 is shipped with a standard PPP configuration.
5.1 Logging into your Lynx L-320
To configure your Lynx L-320, open your web browser. You may get an error
message at this point; this is normal.
1. Type the default IP address (192.168.1.1) or login.router on on the
web address bar.
2. Press the Enter key and the following screen will appear.
Note: Before sitting up your Lynx L-320, make sure you have followed
the steps detailed in your Quick Guide. You should have your computer
configured for DHCP mode and have proxies disabled on your browser.
Upon accessing the Lynx L-320, if the browser still displays a login
redirection screen, you should check your browser’s settings and
ensure that the JavaScript support is enabled. If the screen shown in
Figure 1-5 is not attainable, you must delete your temporary Internet
files to clear the web cache.
Figure 1-3: Setup Page

14
Upon entering the default IP address or the short-cut name (login.router), if
the user is first time login, the user will be brought to the “Basic” page. See
Fig 1.3.The Basic page is meant for basic users whom only require easy
connectivity to the Internet without worrying about any other advance
configuration setting. If you are in doubt for what content to enter for the
Protocol, VPI and VCI, please contact your Service Provider for assistance.
For those who have their routers configured, you will be directed to the
“Basic Home” page. See Fig 1-4.
Figure 1-4: Basic Home Screen
5.2 Basic
If you have already configured your router and wish to change your current
configuration, click on the ‘Setup’ link. Fig 1-5 will appear.

Figure 1-5: Basic Home Page
Click on Apply after entering your settings and then click on Save.
Note: after clicking on Apply, please be sure to click on “Save”
to register the username/password or any other changes.
5.3 LAN / DHCP Configuration
On one side of your Lynx L-320, you have your own Local Area network
(LAN) connections. This is where you plug in your local computers to the
Lynx L-320. The Lynx L-320 is normally configured to automatically provide
all the PC's on your network with Internet addresses.
To enable or disable DHCP, Click setup. Under LAN Setup, select DHCP
Configuration. This will bring up the screen shown in Fig 1-6. The Start IP
Address is where the DHCP server starts issuing IP addresses. This value
must be greater than the Lynx L-320 IP address value. For example if the
Lynx L-320 IP address is 192.168.1.1 (default) than the starting IP address
must be 192.168.1. 2 (or higher). The End IP Address is where the DHCP
server stops issuing IP addresses. The ending address cannot exceed a

16
subnet limit of 254. Hence the max value for our default gateway is
192.168.1.254. If the DHCP server runs out of DHCP addresses, users will
not get access to network resources. If this happens you can increase the
Ending IP address (to the limit of 255) or reduce the lease time. The Lease
Time is the amount of time a network user will be allowed connection to the
Lynx L-320 with their current dynamic IP address. The amount of time is in
units of minutes; the default value is 3600 minutes (60 hours). Note: If you
change the start or end values, make sure the values are still within the
same subnet as the gateways IP address. In other words, if the gateways IP
address is 192.168.1.1 (default) and you change the DHCP start/end IP
addresses to be 192.128.1.2/192.128.1.100, you will not be able to
communicate to the Lynx L-320 if your PC has DHCP enabled. In addition to
the DHCP server feature, the Lynx L-320 supports the DHCP relay function.
When the Lynx L-320 is configured as DHCP server, it assigns the IP
addresses to the LAN clients. When the Lynx L-320 is configured as DHCP
relay, it is responsible for forwarding the requests and responses negotiating
between the DHCP clients and the server.
By turning off the DHCP server and relay the network administrator must
carefully configure the IP address, Subnet Mask and DNS settings of every
computer on your network. Do not assign the same IP address to more than
one computer and your Lynx L-320 must be on the same subnet as all the
other computers.
Figure 1-6: LAN / DHCP Configuration

5.4 Diagnostic Test
Diagnostic Test is used for investigating whether the Lynx L-310 is properly
connected to the WAN Network. See Fig 1-7. This test may take a few
seconds to complete. To perform the test, select your connection from the
list and press the Test button. Before running this test, make sure you have
a valid DSL link.
Figure 1-7: Diagnostics Test Screen
After running the Diagnostic Test, the screen will indicate that the portion
which pass or fail the test. Please click on the Help links, which will provide
remedy to the problem as shown in Fig 1-8. The purpose of the “Fix It”
button is to restore the router’s VPI and VCI to its originated setting.
Figure 1-8: Diagnostic Test Result screen

18
5.4.1 Ping Test
Once you have your Lynx L-320 configured, ensure you can ping the
network. You can access the Ping Test page by clicking on the “here”
hyperlink in Diagnostic Page. Type the target address that you want to ping.
If your PC is connected to the Lynx L-320 via the default DHCP configuration,
you should be able to Ping the network address 192.168.1.1. See Fig 1-9.
If your ISP has provided their server address, try to ping the address. If the
pings for both the WAN and the LAN sides are complete and you have the
proper protocols configured, you should be able to surf the Internet. By
default when you select ping test, the Lynx L-320 will ping itself 3 times. The
Lynx L-320 passed the Ping test; this basically means that the TCP/IP
protocol is up and running. If this first Ping test does not pass, the TCP/IP
protocol is not loaded for some reason; you should restart the Lynx L-320.
Figure 1-9: Ping Test Screen
5.4.2 Modem Test
This test can be used to check whether your Modem is properly connected to
the Network. Select your connection from the list and press the ‘Test’
button. See Fig 1-10.

19
Figure 1-10: Modem Test
5.5 Advanced
This mode is catered for advance users, a brief explanation of the links are
listed as shown below.
Figure 1-11: Advanced Screen

20
5.5.1 WAN Connection
On the other side of the Lynx L-320 is where your Wide Area Network (WAN)
connection; also referred to as a broadband connection. This WAN connection
is different for every WAN supplier. Most of the configuration you will
perform will be in this area. Local Area Network Connection(s).
5.5.2 New Connection
A new connection is basically a virtual connection. Your Lynx L-320 can
support up to 8 different (unique) virtual connections. If you have multiple
different virtual connections, you may need to utilize the static and dynamic
routing capabilities of the modem to pass data correctly.
Figure 1-12: New Connection (PPPOE Connection Setup)
5.5.3 ADSL Modulation
To configure the DSL modulation type, Click setup. Under WAN Setup, select
Modem Setup. This will bring up the modem setup screen. Leave the default
value if you are unsure or the DSL/ISP did not provide this information. For
most all cases, this screen should not be modified.
