12.3 What You Need To Know

The actual physical connection determines whether the Router ports are LAN or WAN ports. There
are two separate IP networks, one inside the LAN network and the other outside the WAN network
as shown next.
Figure 77 LAN and WAN IP Addresses
The LAN parameters of the Router are preset in the factory with the following values:
• IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If your ISP gives you explicit DNS
server address(es), read the embedded Web Configurator help regarding what fields need to be
configured.

12.3.1 IP Pool Setup

The Router is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to
192.168.1.64. This configuration leaves 31 IP addresses (excluding the Router itself) in the lower
range (192.168.1.2 to 192.168.1.32) for other server computers, for instance, servers for mail,
FTP, TFTP, web, etc., that you may have.

12.3.2 LAN TCP/IP

The Router has built-in DHCP server capability that assigns IP addresses and DNS servers to
systems that support DHCP client capability.

12.3.3 IP Alias

IP alias allows you to partition a physical network into different logical networks over the same
Ethernet interface. The Router supports three logical LAN interfaces via its single physical Ethernet
interface with the Router itself as the gateway for each LAN network.
