LAN Configuration

Before you can access the Router Administrator software using the Ethernet port, you must set up your router for TCP/IP. The following sections describe the router’s TCP/IP setup.

A router that is part of a TCP/IP network requires three basic IP configuration elements: IP address, subnet mask, and default gateway IP address. The router’s IP address must be unique to the network in which the router resides. If the router is part of a publicly routed network (that is, attached to the Internet), the address must be globally unique.

This appendix describes how to configure the TCP/IP settings for the first time starting from the factory-set defaults.

Configuring the Router for TCP/IP

Before you can access the Router Administrator software, you must set the IP address and subnet mask for the controller. The default IP address is 10.0.0.1. You can do this one of four ways:

Setting up your computer with an IP address that is compatible with the controller default of 10.0.0.1, such as 10.0.0.42.

Using address resolution protocol (ARP) to set the address. See Using Address Resolution Protocol on page D-2.

Using Dynamic Host Configuration Protocol (DHCP) to set the address. See Dynamic Host Configuration Protocol Configuration on page D-3.
