Configure the NB9/NB9W’s LAN IP address and subnet mask. Save button only saves the LAN configuration
data. Save/Reboot button saves the LAN configuration data and reboots the NB9/NB9W to make the new
configuration effective.
Field Means
LAN IP Address Default: 192.168.1.1. The LAN IP address of your NB9/NB9W.
LAN Subnet Mask Default: 255.255.255.0. The subnet mask of your NB9/NB9W. A subnet mask is used to
determine what subnet an IP address belongs to. For more information on subnetting see
http://www.ralphb.net/IPSubnet/.
Enable UPnP Universal plug and play (UPnP) allows traffic to pass through the NB9/NB9W for applications
using the UPnP protocol. This feature requires one active WAN connection. In addition, the
client connecting to the NB9/NB9W should support this feature.
UPnP also supports NAT Traversal which can automatically solve many NAT-related
communications problems. UPnP enables applications to assign dynamic port mappings to
the NB9/NB9W and delete them when connections are complete.
A typical example is the MSN Messenger application that runs on Windows. Instead of
manually setting up the port mappings UPnP enables MSN Messenger to make the request
to the NB9/NB9W which will setup these ports dynamically. When MSN Messenger is closed
the port openings will be removed from the NB9/NB9W’s configuration.
Configure the second IP address and subnet mask for LAN interface. It is possible to
configure the second IP address to access the NB9/NB9W on. Once this box is checked you
are able to enter the IP address and subnet mask.
Disable DHCP Server Disables the DHCP server. Only to be done if Static IP address is set up.
Enable DHCP Server Default: Enabled.
Start IP Address Default: 192.168.1.2. The first IP address that will be issued to the first DHCP client
connecting to the NB9/NB9W using Ethernet cable or wirelessly.
End IP Address Default: 192.168.1.254. The last IP address in the DHCP pool to be issued to DHCP clients
connecting to the NB9/NB9W.
