5 Setting the LAN IP Address
This chapter describes how to configure the interfaces on the
ADSL/Ethernet router that communicate with your LAN..
Configuring your LAN IP address
If you are using the ADSL/Ethernet router with multiple PCs on your
LAN, you must connect the LAN via an Ethernet hub to the device's
LAN port, called eth-0.
You must assign a unique IP address to each device port that you
use.
Note
The instructions that follow assume that the device has been
preconfigured to operate in Routing mode, which uses the IP
protocol to determine how to exchange data among your PCs, the
device, and your ISP. If your device is configured in Bridging
mode, its ports do not require IP addresses. The operating mode
displays at the top of the LAN Configuration page and cannot be
changed by the user.
Configuring the LAN IP Address
The LAN IP address identifies the LAN port (eth-0) as a node on
your network; that is, its IP address must be in the same subnet as
the PCs on your LAN.
Definition
A network node can be thought of as any port on the network,
such as the VisionNet 202ER’s LAN port and the network interface
cards on your PCs. See Appendix A for an explanation of
subnets..
You can change the default to reflect the set of IP addresses that
you want to use with your network.
If your network uses a local DHCP server (other than the
ADSL/Ethernet router) to assign IP addresses, you can configure
the device to accept and use a LAN IP address assigned by that
server. In this mode, the ADSL/Ethernet router is considered a
DHCP client of your DHCP server.
Note
The VisionNet 202ER itself can function as a DHCP server for
your LAN computers, as described in Chapter 5, but not for its
own LAN port.
