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 config- ured 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 configura- tion from a DHCP server, the router assigns

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

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
