Configuring LAN Settings
This chapter describes how to configure LAN properties for the LAN interface on the Internet Security Router
that communicates with your LAN computers. You'll learn to configure IP address, DHCP and DNS server for
your LAN in this chapter.
5.1
LAN IP Address
If you are using the Internet Security Router with multiple PCs on your LAN, you must connect the LAN via the
Ethernet ports on the built-in Ethernet switch. You must assign a unique IP address to each device residing on
your LAN. The LAN IP address identifies the Internet Security Router as a node on your network; that is, its IP
address must be in the same subnet as the PCs on your LAN. The default LAN IP for the Internet Security
Router is 192.168.1.1.
Definition
You can change the default to reflect the set of IP addresses that you want to use with your network.

Configuring the LAN IP Address
Follow these steps to change the default LAN IP address.
1. Log into Configuration Manager as administrator, and then click the LAN menu.
When the submenus of LAN Configuration displays, click IP submenu to display the IP Address
configuration page as shown in Figure 5.1.
A network node can be thought of as any interface where a
device connects to the network, such as the Internet Security
Router's LAN port and the network interface cards on your PCs.
See Appendix 13 for an explanation of subnets.
The Internet Security Router itself can function as a DHCP server
for your LAN computers, as described in section 5.2.3 Configuring
DHCP Server, but not for its own LAN port.
Table 5.1. LAN IP Configuration Parameters
Description
The LAN IP address of the Internet Security Router. This IP is used by your
computers to identify the Internet Security Router's LAN port. Note that the
public IP address assigned to you by your ISP is not your LAN IP address.
The public IP address identifies the WAN port on the Internet Security Router
to the Internet.
The LAN subnet mask identifies which parts of the LAN IP Address refer to
your network as a whole and which parts refer specifically to nodes on the
network. Your device is preconfigured with a default subnet mask of
255.255.255.0.
