Hardware

Connect the LAN 1 port to your local network

1 Connect the LAN 1 port to the local

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.

Connect the power

4 Connect the router to a power source

(100-250 V AC) using the provided power supply and cord.

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:

Status LED

Green blinking - router is using factory default settings and ready for configuration.

Red - error, router is not operational.

Figure 2. Check Status and LAN LEDs.

LAN 1 and LAN 2 LEDs

Green - port is operational. Orange - port is down. Check cables.

 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.

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.

Select a Scenario

This guide describes four scenarios in which you can connect the router to the Internet through a DSL or cable modem.

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.

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.

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.

Scenario 3: Existing DHCP Server

In this scenario, your LAN uses an existing DHCP server. You must change the routers default LAN 1 IP address and disable the routers 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.

Figure 4. Scenario 3 - Existing DHCP Server on LAN. For instructions on setting up this scenario,

see page 7.

Figure 5. Scenario 4 - Static IP Address on LAN 2. For instructions on setting up this scenario,

see page 9.

Scenario Descriptions

Scenario 1

LAN PCs Get IP Address from DHCP Server on Router

 The default IP address on the routers 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.
