Chapter 9 LAN

NBG-417N User’s Guide

The actual physical connection determines whether the NBG-417N 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.

LAN and WAN IP Addresses

The LAN parameters of the NBG-417N 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.

The NBG-417N 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 NBG-417N 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.

Refer to 

 for information on IP Address and Subnet Mask.

The NBG-417N has built-in DHCP server capability that assigns IP addresses and DNS servers to 
systems that support DHCP client capability.

Refer to the 

 section for information on System DNS Servers.
