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 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
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.
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.
