Configuring the Router for TCP/IP
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.
You can configure the router’s TCP/IP settings using the menus described in Accessing the
Router Administrator Using the Ethernet Port on page 3-3 . This appendix describes how
to configure the TCP/IP settings for the first time starting from the factory set defaults.
You must initially set up your computer with TCP/IP settings that are compatible with the
router. This lets you access the router and configure it. Since you might not want to change
your computer’s settings, you can alternatively use address resolution protocol (ARP) to
temporarily set them.
Using Address Resolution Protocol
The ARP configuration method requires no IP address re-configuration of any computer
on the network. The ARP command is available in various forms and sometimes with
varying syntax, in UNIX and Windows systems.
All routers are shipped with a unique Media Access Control (MAC) hardware address
(sometimes referred to as a physical address). Chaparral Network Storage MAC addresses
have the format “00-50-13-fx-xx-xx,” where “x-xx-xx” is unique to each router. The
router MAC address can be found on a label on the bottom of the router.
Note: TCP/IP protocol requires that all devices in a subnet have the same
octets, typically for the first three octets. For example, to use the default
Chaparral IP address of 10.0.0.1, other computers on the subnet must be
10.0.0.X, where X is the value between 2 and 255. ARP is useful because
you can temporarily assign a compatible IP address to the router.
