To configure remote management:
1.
Under the Advanced heading on the main menu, select Remote Management. The Remote
Management screen appears:
2.
Select the
Allow Remote Management
check box.
3.
Enter the
Remote User Name
and
Remote Password
that will be required to remotely access
your gateway.
4.
Enter the
Port Number
that will be used for accessing the management interface.
Web browser access normally uses the standard HTTP service port 80. For greater security,
you can specify a custom port by entering that number in the box provided. Choose a number
between 1024 and 65535, but do not use the number of any common service port. The default
is 8080, which is a common alternate for HTTP.
5.
To make sure that you can use remote management even if the wireless voice gateway is reset,
select the
Allow Remote Management after Factory Default Reset
check box.
If you do not select this check box, you will not be able to remotely access the gateway if you
use the Erase feature to revert to the Factory Default settings.
6.
Click
Apply
to have your changes take effect.
When accessing your wireless voice gateway from the Internet, type the WAN IP address of your
gateway into your browser, followed by a colon (:) and the port number. For example, if your
WAN IP address is 134.177.0.123 and you use port number 8080, type the following in your
browser:

Universal Plug and Play (UPnP)
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, 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.
UPnP can be enabled or disabled for automatic device configuration. The default setting for UPnP
is disabled. If disabled, the router will not allow any device to automatically control the resources,
such as port forwarding (mapping), of the router.
Other features of UPnP:
Advertisement Period
. The number entered in this field (in minutes) determines how often
the router will advertise (broadcast) its UPnP information. This value can range from 1 to 1440
minutes. The default period is for 30 minutes.
Shorter durations will ensure that control points have current device status at the expense
of additional network traffic.
Longer durations may 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. A hop is the number of steps 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 advertisement time to live is 4 hops, which should be fine for most home
networks. If you notice that some devices are not being updated or reached correctly, then you
may need to increase this value a little.
UPnP Portmap Table.
The UPnP Portmap Table displays the IP address of each UPnP device
that is currently accessing the router and which ports (internal and external) that device has
opened. The UPnP Portmap Table also displays what type of port is opened and if that port is
still active for each IP address.
