LAN and WAN IP Addresses

The actual physical connection determines whether the NBG4115 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 60 LAN and WAN IP Addresses

The LAN parameters of the NBG4115 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.

IP Pool Setup

The NBG4115 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 NBG4115 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 4.5.7 on page 50 for information on IP Address and Subnet Mask.

LAN TCP/IP

The NBG4115 has built-in DHCP server capability that assigns IP addresses and

DNS servers to systems that support DHCP client capability.

Refer to the Section 4.5.8 on page 50 section for information on System DNS

Servers.

None of the LEDs turn on. 24.3 NBG4115 Access and Login I dont know the IP address of my NBG4115. I forgot the password. I cannot see or access the Login screen in the Web Configurator. I can see the Login screen, but I cannot log in to the NBG4115. 24.4 Internet Access I cannot access the Internet. The Internet connection is slow or intermittent. 24.5 Resetting the NBG4115 to Its Factory Defaults You will lose all of your changes when you push the RESET button. 24.6 Wireless Router/AP Troubleshooting I cannot access the NBG4115 or ping any computer from the WLAN (wireless AP or router). I set up URL keyword blocking, but I can still access a website that should be blocked. I can access the Internet, but I cannot open my network folders. I can access the Web Configurator after I switched to AP mode.
