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

LKR-604
33
DHCP Client List
The DHCP client list allows you to see which clients are connected to
the LKR-604 Broadband Router via IP address, host name, and MAC
address.
LKR-604
34
NAT
Network Address Translation (NAT) allows multiple users at the local
site to access the Internet through a single public IP address. NAT can
also prevent hacker attacks by mapping local addresses to public
addresses for key services such as the Web or FTP.
Special Application
Some applications require multiple connections, such as Internet
gaming, video conferencing, and Internet telephony. These applications
cannot work when Network Address Translation (NAT) is enabled.
When users send this type of request to your network via the Internet,
the LKR-604 Broadband Router will forward those requests to the
appropriate PC. If you need to run applications that require multiple
connections, specify the port normally associated with an application in
the "Trigger Port" field, select the protocol type as TCP or UDP, then
enter the public ports associated with the trigger port to open them for
inbound traffic.
z TCP (Transmission Control Protocol) - A method (protocol) used
along with the Internet Protocol (Internet Protocol) to send data in
the form of message units between computers over the Internet.
While IP takes care of handling the actual delivery of the data,
TCP takes care of keeping track of the individual units of data
(called packets) that a message is divided into for efficient routing
through the Internet.
z UDP (User Datagram Protocol) - A communications method
(protocol) that offers a limited amount of service when messages
are exchanged between computers in a network that use the
Internet Protocol IP). UDP is an alternative to the TCP and,
together with IP, is sometimes referred to as UDP/IP. Like the
Transmission Control Protocol, UDP uses the Internet Protocol to
actually get a data unit (called a datagram) from one computer to
another. Unlike TCP, however, UDP does not provide the service
LKR-604
35
of dividing a message into packets (data grams) and
reassembling it at the other end. Specifically, UDP doesn't
provide sequencing of the packets that the data arrives in. This
means that the application program that uses UDP must be able
to make sure that the entire message has arrived and is in the
right order. Network applications that want to save processing
time because they have very small data units to exchange (and
therefore very little message reassembling to do) may prefer UDP
to TCP
LKR-604
36
Virtual Server
The virtual server option allows you to define port number on your
LKR-604 Broadband Router for redirection to an internal LAN IP
address. This feature is useful for hosting online services such as FTP
or Web servers.
LKR-604
37
Firewall
The LKR-604 Broadband Router provides extensive Firewall protection
by restricting connection parameters to limit the risk of hacker attacks
and by defending against a wide array of common hacker attacks.
The LKR-604 Broadband Router provides packet filtering rules by
restricting service ports, IP address or MAC address. However, for
applications that require unrestricted access to the Internet, you may
configure a specific client/server as a demilitarized zone (DMZ)
Discard PING From WAN Side
When "Discard PING from WAN side" is checked, it causes the public
WAN IP address on the LKR-604 Broadband Router to ignore ping
commands. Pinging public WAN IP addresses is a common method
used by hackers to test whether the WAN IP address is valid.
LKR-604
