network or the Ethernet port of a PC,
using the provided blue cable.
2 Set the HUB/PC switch to Hub when
connecting to a network hub or Ethernet
switch, and PC when connecting
directly to a PC.
Connect the LAN 2 port to your
DSL or cable modem
3 Connect the LAN 2 port to your DSL or
cable modem. Use the appropriate cable
that came with your modem.

Check the LEDs
If the Status, LAN 1, and LAN 2 LEDs are
all green, the router begins to assign a set of
pre-configured IP addresses to your local
network using its DHCP server.
If any LEDs are red, orange, or off:
Make sure the PC/Hub switch is set
correctly, as described in step 2 above.
Make sure all the cables are securely
connected to the correct devices as
described in the steps above.
LAN 1 and LAN 2 LEDs
Green - port is operational.
Orange - port is down. Check cables.
Status LED
Green blinking - router is using factory default settings
and ready for configuration.
Red - error, router is not operational.

About the Console Port
You can use the console port to manage the
router with Local Management, through a
directly connected workstation. See the Online
Documentation on the Intel® Device View CDROM for information about managing the router
if you do not have a Windows-based operating
system, or if you are using Telnet to manage the
router from a remote location.

Scenario 1: Router is the DHCP
Server
In this scenario, the LAN PCs are configured as DHCP clients, and you do not need
to do any configuration other than installing
the router and connecting cables. As long as
the PCs on your LAN request IP configuration from a DHCP server, the router assigns
a preset range of IP addresses to your LAN.
See page 4.
About scenarios 2, 3, and 4
Before configuring the router for these
scenarios, you must install Intel® Device
View as described on page 5.
Scenario 2: Cable Modem
In this scenario, as shown in Figure 8 on
page 6, you connect the LAN 2 port to a
cable modem. Your ISP (Internet service
provider) provides a dynamic IP address
and a name to identify the router, which you
must configure. See page 6.

Figure 3. Scenario 1 - LAN PCs Get IP Address from
Router’s DHCP Server. You can access the Internet
through your DSL or cable modem once you have
connected the router cables. See page 4 for information.
Figure 4. Scenario 3 - Existing DHCP Server on
LAN. For instructions on setting up this scenario,
see page 7.
7068
Scenario 3: Existing DHCP Server
In this scenario, your LAN uses an existing
DHCP server. You must change the routers
default LAN 1 IP address and disable the
routers DHCP server. See page 7.
Scenario 4: Static IP from ISP
In this scenario, the LAN 2 port uses a static
(permanent) IP address assigned by the ISP
each time the modem connects to the
Internet. You can also configure the router
to allow access to internal servers on the
local network from the Internet (such as an
e-mail or Web server). See page 9.

LAN 2. For instructions on setting up this scenario,

Scenario Descriptions
Scenario 1
LAN PCs Get IP Address from
DHCP Server on Router
The default IP address on the routers LAN 1
port is 192.168.1.1. The router automatically
assigns IP addresses sequentially to the hosts
(PCs and servers, for example) on your LAN,
using the address range from 192.168.1.2 to
192.168.1.254.
The LAN 2 port accepts an IP address from the
ISP, and the router automatically configures
your LAN. As long as your DSL or cable
modem is working properly and has a connection to the Internet, you are finished with
setting up this scenario. The PCs on your LAN
can now access the Internet.

In this scenario, the router automatically maps the
dynamic IP address you receive from the ISP to the
internal IP addresses it assigns to the LAN.
The NAT mappings provide adequate security to
prevent access to your network from the Internet.
However, you can set up firewall filters to limit
access to the Internet from the internal LAN (for
example, to allow LAN users access to only e-mail
and WWW traffic through the Internet connection).
See page 10 for more information.
Table 1. Router’s factory default settings. The
settings shown in this table allow the router to work in
this scenario with no further configuration.
To reset the router to factory defaults:
1 Press the Recovery button located on the
back of the router. After a few seconds the
Status LED blinks orange.
2 Press and hold the Recovery button until the
LEDs begin to blink in sequence. When the
Status LED blinks green, the router is set to
factory default.
