Product Overview
Chapter 1: Product Overview
Thank you for choosing the Linksys by Cisco EtherFast
Cable/DSL Router with 8-Port Switch. The Router lets
you access the Internet through its eight switched ports.
You can also use the Router to share resources such as
computers, printers and files. A variety of security features
help to protect your data and your privacy while online.
Security features include a Stateful Packet Inspection (SPI)
firewall and NAT technology. Configuring the Router is
easy using the provided browser-based utility.
Front Panel
QoS (Green) The QoS LED lights up when the
QoS feature is active.
Back Panel
Reset There are two ways to reset the Router to
its factory default settings. Use a straightened
paper clip or similar object to press and hold the
Reset button for approximately five seconds.
You can also restore the defaults from the
Administration > Factory Defaults screen of the
Router’s web-based utility.
Internet The Internet port is where you will
connect your cable or DSL Internet connection.
1-8 These Ethernet ports (1, 2, 3, 4, 5, 6, 7, 8)
connect the Router to computers on your wired
network and other Ethernet network devices.
Power The Power port is where you will
connect the power adapter.
Power (Green) The Power LED lights up and
will stay on while the Router is powered on.
It flashes when the Router goes through its
self-diagnostic mode during every boot-up or
upgrades its firmware.
1-8 (Green) These numbered LEDs correspond
with the numbered ports on the Router’s back
panel. These LEDs have a dual function. If the
LED is continuously lit, the Router is successfully
connected to a device through that port. A
flashing LED indicates network activity over
that port.
Internet (Green) The Internet LED lights up
when there is a connection made through the
Internet port. A flashing LED indicates network
activity over the Internet port.

Chapter 2: Advanced Configuration
After setting up the Router with the Setup Wizard (located
on the CD-ROM), the Router will be ready for use. However,
if you’d like to change its advanced settings, use the
Router’s web-based utility. This chapter describes each
web page of the utility and each page’s key functions. You
can access the utility via a web browser on a computer
connected to the Router.
The web-based utility has these main tabs: Setup, Security,
Applications & Gaming, Administration, and Status.
Additional tabs will be available after you click one of the
main tabs.

Applications & Gaming > Port Triggering
The Port Triggering screen allows the Router to watch
outgoing data for specific port numbers. The IP address of
the computer that sends the matching data is remembered
by the Router, so that when the requested data returns
through the Router, the data is pulled back to the proper
computer by way of IP address and port mapping rules.
When users send these types of requests to your network via
the Internet, the Router will forward those requests to the
