Chapter 4: Quick Installation Guide
After connecting the TL-R402M router into your network, you should configure it. This
chapter describes how to configure the basic functions of your TL-R402M Cable/DSL
Router. These procedures only take you a few minutes. You can access the Internet via
the router immediately after it has been successfully configured.
4.1 TCP/IP configuration
The default IP address of the TL-R402M Cable/DSL Router is 192.168.1.1, and the
default Subnet Mask is 255.255.255.0. These values can be seen from the LAN, and can
be changed as your desire. As an example, we use the default values for description in
this guide.
Connect the local PCs to the LAN ports on the router. There are then two means to
configure the IP address for your PCs.
Configure the IP address manually
1) Set up the TCP/IP Protocol for your PC(s). If you need instructions as to how to
do this, please refer to
2) Configure the network parameters. The IP address is 192.168.1.xxx ("xxx" is
from 2 to 254), Subnet Mask is 255.255.255.0, and Gateway is 192.168.1.1
(The router's default IP address)
Obtain an IP address automatically
1) Set up the TCP/IP Protocol in "Obtain an IP address automatically" mode on
your PC(s). If you need instructions as to how to do this, please refer to
Appendix B: "Configuring the PCs."
2) Power off the router and PC(s). Then turn on the router, and restart the PC(s).
The built-in DHCP server will assign IP addresses for the PC(s).
Appendix B: "Configuring the PCs."
Now, you can run the Ping command in the command prompt to verify the network
connection between your PC(s) and the router. The following example is in Windows
2000.
Open a command prompt, and type ping 192.168.1.1, then press Enter.
Figure 4-1 Successful result of Ping command
If the result displayed is similar to what is shown in figure 4-1, the connection between

your PC and the router has been established.
Figure 4-2 Failed result of Ping command
If the result displayed is similar to what shown in figure 4-2, it means that your PC has
not connected to the router. If so, refer to the following steps for a solution.
1. Is the connection between your PC and the router correct?
Note: The Link/Act LEDs of LAN port on the router and LEDs on your PC's adapter
should be lit.
2. Is the TCP/IP configuration for your PC correct?
Note: If the router's IP address is 192.168.1.1, your PC's IP address must be within
the range of 192.168.1.2 ~ 192.168.1.254, the gateway must be 192.168.1.1
4.2 Quick Installation Guide

5.6.2 Port Triggering
Some applications require multiple connections, like Internet games, video
conferencing, Internet calling and so on. These applications cannot work with a pure
NAT router. Port Triggering is used for some of these applications that can work with an
NAT router. You can set up Port Triggering on this page shown in figure 5-15:
Figure 5-15 Port Triggering
Once configured, operation is as follows:
1. A local host makes an outgoing connection using a destination port number defined
in the Trigger Port field.
2. The router records this connection, opens the incoming port or ports associated
with this entry in the Port Triggering table, and associates them with the local host.
3. When necessary the external host will be able to connect to the local host using
one of the ports defined in the Incoming Ports field.
Trigger Port - The port for outgoing traffic. An outgoing connection using this port
will "Trigger" this rule.
- 22 -
TL-R402M Cable/DSL Router User Guide
Trigger Protocol - The protocol used for Trigger Ports, either TCP,UDP, or All (all
protocols supported by the router).
Incoming Ports Range - The port or port range used by the remote system when it
responds to the outgoing request. A response using one of these ports will be
forwarded to the PC that triggered this rule. You can input at most 5 groups of ports
(or port section). Every group of ports must be apart with ",". For example,
2000-2038, 2050-2051, 2085, 3010-3030.
Incoming Protocol - The protocol used for Incoming Ports Range, either TCP or
UDP, or ALL (all protocols supported by the router).

list.
To add a new rule, enter the following data on the Port Triggering screen.
1. Enter a port number used by the application when it generates an outgoing
request.
2. Select the protocol used for Trigger Port from the pull-down list, either TCP, UDP,
or All.
3. Enter the range of port numbers used by the remote system when it responds to
the PC's request.
4. Select the protocol used for Incoming Ports Range from the pull-down list, either
TCP, UDP, or All.
5. Select the Enable checkbox to enable.
6. Click the Save button to save the new rule.
There are many popular applications in the Popular Application list. You can select it
and the ID, then click the Copy to button, the application will fill in the Trigger Port,

connection of other hosts on LAN will be refused.
3. Incoming Port Range cannot overlap each other.
5.6.3 DMZ
The DMZ host feature allows one local host to be exposed to the Internet for a
special-purpose service such as Internet gaming or videoconferencing. DMZ host
forwards all the ports at the same time. Any PC whose port is being forwarded must have
its DHCP client function disabled and should have a new static IP address assigned to it
because its IP address may change when using the DHCP function. You can set up DMZ
host on this page shown in figure 5-16:
