Quick installation
Hardware connection
Before you begin, turn the power off for all devices.
These include your computer(s), your LAN hub/switch (if
applicable), and the ASUS SL1200.
Step 1: Connect an ADSL or a cable modem
To connect the router
Connect one end of the Ethernet cable to the port labeled WAN on the
rear panel of the device. Connect the other end to the Ethernet port on the
ADSL or cable modem.

ASUS SL1200
Step 2: Connect computers or a LAN
If your LAN has four or less than four computers, you can use an Ethernet
cable to connect computers directly to the built-in switch on the device.
You should attach one end of the Ethernet cable to any of the port labeled
LAN1 – LAN4 on the rear panel of the device and connect the other end to
the Ethernet port of a computer.
If your LAN has more than four computers, you can attach one end of an
Ethernet cable to a hub or a switch, such as an uplink port (refer to the hub
or switch documentations for instructions), and the other to the Ethernet
switch port (labeled LAN1 – LAN4) on the router.
You can use either a crossover or a straight-through
Ethernet cable to connect the built-in switch and computers,
hubs or switches.
Step 3: Attach the power adapter
Connect the power adapter to the POWER connector on the back of the
device and plug the adapter to a wall outlet or a power strip.
Step 4: Turning on the ASUS SL1200
After plugging in, the router will automatically turn on. Turn on your ADSL
or cable modem, your computer(s), and any LAN devices such as hubs or
switches.

Conguring Your Computers
This section provides instructions for conguring the Internet settings on
your computers to work with the router.
Before you begin
By default, the ASUS SL1200 automatically assigns all required Internet
settings to your PCs. You only need to configure the PCs to accept the
information when it is assigned.
In some cases, you may want to congure network settings
manually to some or all of your computers rather than allow
the Internet Security Router to do so. See Assigning static
IP addresses to your PCs on page 10 for instructions.
If you have connected your PC via Ethernet to the router, follow the
instructions that correspond to the operating system installed on your PC.

Assigning static IP addresses to your PCs
In some cases, you may want to assign IP addresses to some or all of
your PCs directly (often called “statically”), rather than allowing the ASUS
SL1200 to assign them. This option may be desirable (but not required) if:
• You have obtained one or more public IP addresses that you want
to always associate with specic computers (for example, if you are
using a computer as a public web server).
• You maintain different subnets on your LAN.
However, during the rst time conguration of your router, you must
assign an IP address in the 192.168.1.0 network for your PC, such
as 192.168.1.2. This is in order to establish connection between
the router and your PC as the default LAN IP on the router is pre-
congured as 192.168.1.1. Enter 255.255.255.0 for the subnet mask
and 192.168.1.1 for the default gateway. These settings may be
changed later to reect your true network environment.
On each PC to which you want to assign static information, follow the
instructions on pages 6 to 9 relating only to checking for and installing
the IP protocol. Once it is installed, continue to follow the instructions
for displaying each of the Internet Protocol (TCP/IP) properties.
Instead of enabling dynamic assignment of the IP addresses for the
computer, DNS server, and default gateway, click the radio buttons
that enable you to enter the information manually.
Your PCs must have IP addresses that place them in the
same subnet as the Internet Security Router’s LAN port. If
you want to manually assign IP information to all your LAN
PCs, you can follow the instructions in Conguring the
LAN IP Address.
Conguring the LAN IP Address
To change the default LAN IP address
1. Log into the Configuration Manager as administrator, and then click
LAN -> IP. The IP Address conguration page is displayed as shown in
Figure 2.
