N150 Wireless ADSL2+ Modem Router N150RM
Normal web browser access uses the standard HTTP service port 80. For greater
security, enter a custom port number for the remote web management interface. Choose
a number from 1024 to 65535, but do not use the number of any common service port.
The default is 8080, which is a common alternate for HTTP.
5. Click Apply to have your changes take effect.
6. When accessing your modem router from the Internet, type your modem router’s WAN IP
address into your browser’s address or location field followed by a colon (:) and the custom
port number. For example, if your external address is 134.177.0.123 and you use port
number 8080, enter http://134.177.0.123:8080 in your browser.
Universal Plug and Play
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers,
to access the network and connect to other devices as needed. UPnP devices can
automatically discover the services from other registered UPnP devices on the network.
If you use applications such as multiplayer gaming, peer-to-peer connections, or real-time

you should enable UPnP.
 To turn on Universal Plug and Play:
1.
Select Advanced > UPnP. The UPnP screen displays.

router does not allow any device to automatically control the resources, such as port
forwarding (mapping) of the modem router.
Advertisement Period . The advertisement period is how often the modem router
broadcasts its UPnP information. This value can range from 1 to 1440 minutes. The
default period is 30 minutes. Shorter durations ensure that control points have current
device status at the expense of more network traffic. Longer durations can compromise
the freshness of the device status, but can significantly reduce network traffic.
Advertisement Time to Live . The time to live for the advertisement is measured in hops
(steps) for each UPnP packet sent. The time to live hop count is the number of steps a
broadcast packet is allowed to propagate for each UPnP advertisement before it
disappears. The number of hops can range from 1 to 255. The default value for the
