The UPnP Screen
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for
simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a
network, obtain an IP address, convey its capabilities and learn about other devices on the network.
In turn, a device can leave a network smoothly and automatically when it is no longer in use.
See
page 120
for more information on UPnP.
Use the following screen to configure the UPnP settings on your VMG. Click
Network Setting >
Home Networking
> UPnP
to display the screen shown next.

Select
Enable
to activate UPnP. Be aware that anyone could use a UPnP application to open
the web configurator's login screen without entering the VMG's IP address (although you
must still enter the password to access the web configurator).
UPnP NAT-T
Select
Enable
to allow UPnP-enabled applications to automatically configure the VMG so
that they can communicate through the VMG by using NAT traversal. UPnP applications
automatically reserve a NAT forwarding port in order to communicate with another UPnP
enabled device; this eliminates the need to manually configure port forwarding for the UPnP
enabled application.
The table below displays the NAT port forwarding rules added automatically by UPnP NAT-T.
#
This is the index number of the UPnP NAT-T connection.
Description
This is the description of the UPnP NAT-T connection.
Destination IP
Address
This is the IP address of the other connected UPnP-enabled device.
External Port
This is the external port number that identifies the service.

also configure firewall rules to control access to the LAN's logical network (subnet).
If your ISP provides the Public LAN service, the VMG may use an LAN IP address that can be
accessed from the WAN.

The STB Vendor ID Screen
Set Top Box (STB) devices with dynamic IP addresses sometimes don’t renew their IP addresses
before the lease time expires. This could lead to IP address conflicts if the STB continues to use an
IP address that gets assigned to another device. Use this screen to configure the Vendor IDs of
connected STBs, which have the VMG automatically created static DHCP entries for them when they
request IP addresses.
