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). 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:

1Press the Recovery button located on the back of the router. After a few seconds the Status LED blinks orange.

2Press 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.
