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 connec-
tion to the Internet, you are finished with
setting up this scenario. The PCs on your LAN
can now access the Internet.
Network address translation (NAT) and
security
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).

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.
