Applications
• Local Network Access
The LKR-604 Broadband Router provides connectivity to 10/100 Mbps
wired-Ethernet devices that making it easy to create a network in small
offices or homes.
• Internet Access
The LKR-604 supports Broadband Internet access through a CABLE
or DSL connection. Since many DSL providers use PPPoE to establish
communications with end users, the LKR-604 includes a built-in client
for these protocols, eliminating the need to install these services on
your computer.
• Shared Internet Connection
The LKR-604 shares a single Broadband Internet connection using only
one ISP account, multiple users on your network can access the
Internet at the same time.
• Virtual Server
If you have a static public IP address, you can set the LKR-604 to act as
a virtual host for network address translation. Remote users access
various services at your site using a static IP address. Then, depending
on the requested service (or port number), the LKR-604 routes the
request to the appropriate server (at a local private IP address). This
secures your network from direct attack by hackers, and provides more
flexible management by allowing you to change internal private IP
addresses without affecting outside access to your network.

LKR-604
• DMZ Host Support
Allows a networked computer to be fully exposed to the Internet. This
function is used when NAT or Firewall security prevent the special
application feature from functioning correctly.
• Virtual Private Network (VPN)
The LKR-604 supports most commonly used VPN protocols — PPTP
and IPSec. These protocols allow remote users to establish a secure
VPN connection over the Internet to their corporate network. If your
Internet service provider supports PPTP and IPSec protocols, then
these protocols can be used to create an authenticated and encrypted
VPN tunnel for passing secure data over the Internet (i.e., a traditionally
shared data network).

Network Settings
Accessing the Internet through the LKR-604 Internet Broadband Router,
you have to properly configure the network settings of your computers
to use the same IP subnet as the LKR-604.
The default IP address of the LKR-604 is 192.168.0.1, and the default
subnet mask is 255.255.255.0. These addresses can be changed as
needed, but the default values are used in this manual. If the network
TCP/IP settings of your computer has not yet been configured, you can
refer to Configuring PC Network TCP/IP Settings and configure it.
For example:
1. Configure your computer using a static IP address as 192.168.0.10,
subnet mask is 255.255.255.0 and gateway as 192.168.0.1, since the
default IP address of the LKR-604 is 192.168.0.1, the IP address of
your computer must be 192.168.0.X (where “X” is a number between
2 and 254.). Each computer on your network must have a different IP
address within the range. The default gateway must be 192.168.0.1
(the default IP address of the LKR-604).
2. Or more conveniently, configure your computer to obtain TCP/IP
settings automatically from the DHCP server feature of the LKR-604.
Disable HTTP Proxy
In order to access and view the LKR-604’s configuration web pages,
you need to verify that the “HTTP Proxy” feature of your web browser
is disabled.

Configuring The LKR-604
First, make sure that the network connections are functioning normally.
The LKR-604 Internet Broadband Router can be configured using
Internet Explorer 5.0 or above or Netscape Navigator 5.0 or above.
Startup and Login
Open your web browser and type in the IP address of the LKR-604 into
the Location (for Netscape) or
Address (for IE) field and press
“Enter”. The default IP address of
the LKR-604 is 192.168.0.1
After the connection is established,
a logon screen will pop up. To log in
as an administrator, type in the user
name “admin” and the password
(by default, there is no password),
then click the “LOGIN” button, the
web-based management interface
will appear.
Two setup options appear: Quick Setup and Advanced Setup. It is
recommended that you use Quick Setup if you are a beginner. It will
lead you through the step-by-step configuration.
