Figure 75 LAN and WAN IP Addresses
The LAN parameters of the NBG5615 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.
13.3.1 IP Pool Setup
The NBG5615 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 NBG5615 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.
13.3.2 LAN TCP/IP
The NBG5615 has built-in DHCP server capability that assigns IP addresses and DNS servers to
systems that support DHCP client capability.
13.3.3 IP Alias
IP alias allows you to partition a physical network into different logical networks over the same
Ethernet interface. The NBG5615 supports three logical LAN interfaces via its single physical
Ethernet interface with the NBG5615 itself as the gateway for each LAN network.
