9.3 What You Need To Know
The actual physical connection determines whether the NBG4604 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 65 LAN and WAN IP Addresses
The LAN parameters of the NBG4604 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.
9.3.1 IP Pool Setup
The NBG4604 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 NBG4604 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 Section 4.4.6 on page 49 for information on IP Address and Subnet Mask.
9.3.2 LAN TCP/IP
The NBG4604 has built-in DHCP server capability that assigns IP addresses and
DNS servers to systems that support DHCP client capability.
Refer to the Section 4.4.7 on page 50 section for information on System DNS
Servers.
