Introduction
1.1 An Overview of Kx ADSL Router
The Kortex Kx ADSL Router functions as an IEEE 802.3 Ethernet-based broadband IP sharing router. It
provides one 10/100 Dual Speed Ethernet port for connection to a home or small office network and one
10Mb Ethernet port for a DSL Modem, Cable Modem, or other Broadband access device.
Kx ADSL Router provides the safety and security of ports blocking and a natural firewall as well as
integrated NAT support that allows up to 32 users to share a single Internet Connection. Static address
support, integrated client/server DHCP, and device name support will allow Kx ADSL Router to connect
to nearly any Broadband provider, and at the same time simplify local area network settings.
The product has one local 10/100 Dual Speed Ethernet port and one 10Mb Ethernet global port. The
local port can be connected directly to a single computer to provide added security from hackers and
others on the Internet or it can be connected to an Ethernet or Fast Ethernet hub or switch to provide
Internet Sharing and Firewall protection to a local area network. The global port can be connected to any
Cable, DSL, or Broadband modem with an Ethernet port.
Kx ADSL Router provides two levels of security support. First, it masks local users’ IP addresses from
others on the Internet making it much more difficult for a hacker to target a machine on your network.
Secondly it can block and redirect certain ports to limit the services that outside users can access. The
user, to ensure that games and other Internet applications will run properly, can open specific ports.
Unlike proxy server or NAT software that requires the software server to remain visible on the Internet,
no local computers are directly externally visible when using Kx ADSL Router. Also Kx ADSL Router,
like broadband, is always on, removing the need to constantly boot a software server when access is
desired from a client. No client software is required to connect to Kx ADSL Router so it will support any
operating system that can connect to a network whether PC or Apple based. Telnet and Terminal setup
are operating system independent. However, the Configuration Program of Kx ADSL Router must run
on Microsoft Windows (95, 98, NT, 2000 or ME).
Integrated DHCP services allow up to 128 users to get their IP address automatically on boot up from this
Kx ADSL Router. Client machines require no software, simply set them to accept a dynamically
assigned IP address and reboot. Each time they are powered up Kx ADSL Router will recognize them
and set their IP address to instantly connect them to the LAN.
For advanced users Virtual Service support allows Kx ADSL Router to provide limited visibility to local
machines and their services as dictated by the user. An ISP provided IP address can be set to Kx ADSL
Router and then specific services can be rerouted to specific computers on the local network. For instance,
a dedicated web server can be connected to the Internet via Kx ADSL Router and then incoming requests
for HTML that are received by the product can be rerouted to the original server, even though the server
now has a different IP address. In this example, Kx ADSL Router is on the Internet and vulnerable to
attacks, but the server is protected.

Virtual Service can also be used to re-task services to multiple servers. For instance, Kx ADSL Router
can be set to allow separate FTP, Web, and Multiplayer game servers to share the same Internet-visible IP
address while still protecting the servers and local users from hackers.

Using Kx ADSL Router
2.1 Cautions for using Kx ADSL Router
Do not place Kx ADSL Router high humidity and high temperature.
Do not use the same power source for Kx ADSL Router with other equipment.
Do not open or repair the case yourself. If the Kx ADSL Router is too hot, turn off the power
immediately and have a qualified serviceman repair it.
Place the Kx ADSL Router on the stable surface.
Only use the power adapter that comes with the package.

(port)
Connect the supplied RS-232 cable to this port when
connecting to a PC’s RS-232 port (9-pin serial port).
Global
(RJ-45
connector)
Connect an UTP Ethernet cable or crossover cable to
this port when connecting to the Internet or making
other WAN connections.
Local
(RJ-45
connector)
Connect an cross-over Ethernet cable to this port when
connecting to a LAN such as an office or home
network.
2.4 Cabling
The most common problem associated with Ethernet is bad cabling. Make sure that all connected devices are
turned on. On the top of Kx ADSL Router is a bank of LEDs, as a first check verifies that the LAN Link and
WAN Link LEDs are lit and green. If they are not, verify that you are using the proper cables.
Kx ADSL Router’s ports are wired just like a Network Adapter’s port. From the product directly to a PC, the
cable should be an Ethernet crossover cable. From the product to a hub or switch, the cable should be an
Ethernet straight through cable to a normal hub/switch port, or an Ethernet crossover cable to an uplink port.
For the product to a cable/DSL modem, it is most common to use a crossover, and it is recommended that you
use the same cable as supplied by your modem maker.
