Default: 192.168.1.1. The LAN IP address of your NB9/NB9W.
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/.
Universal plug and play (UPnP) allows traffi c 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
confi guration.
Confi gure the second IP address and subnet mask for LAN interface. It is possible
to confi gure 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.
Disables the DHCP server. Only to be done if Static IP address is set up.
Default: Enabled.
