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.
