Port Filtering

Port Filtering allows you to block outgoing Internet connections and permit only allowed

applications to access the Internet. You can also customize a list of allowed applications which

permits only certain programs to connect to the Internet.

Click

ON

to turn on Port Filtering. When the feature is turned on, you must select a port filtering

application in the

Applications

list to allow that application to connect to the Internet. For example,

if you select VPN in the Applications list but do not select HTTP, you can connect to a VPN server but

you cannot connect to a web page using your Internet browser.

Click

OFF

to turn off Port Filtering. When the feature is turned off, any application can connect to the

Internet.

The Port Filtering menu contains the following sections:

•

Applications

— Turn on each port filtering application that needs to be able to access the

Internet by checking the box next to one or more applications. When port filtering is turned

on, all other applications are blocked.

•

Custom Applications

— You can define your own applications, and then turn them on or

off as needed. To define an application, you need to know the outgoing ports used by the

application.

72

Add a Custom Application

To add a custom application:

➊

Click

Add Custom Application

to add a new custom application to the list of allowed

applications. You can define and turn on custom Port Filtering applications. You need to

know details of the traffic used and generated by the applications you wish to define.

NOTE

The

Add Custom Application

option is only available when the port filtering is turned on. You

can add up to ten custom applications.

The Custom Port Filtering page uses check boxes to turn on port filtering for custom

applications. Similar to the Applications list, you must turn on custom applications so they

can connect to the Internet.

➋

Enter the beginning of the range of port numbers used by outgoing traffic for the custom

application being added in the

Start Port

field.

➌

Enter the end of the range of port numbers in the

End Port

field. If the port is a single port

instead of a range, type the same value for both the

Start Port

and the

End Port

.

➍

Select the protocol used by each port range from the

Protocol

dropdown menu. Choose

from Transmission Control Protocol (TCP), User Datagram Protocol (UDP), or both. Click

Save

Changes

to save any changes made to the custom applications.

73

➎

Select the

Delete

checkbox next to any custom application you wish to remove and click

Save Changes

.

NOTE

Click on the Port Filtering menu tab again to remove deleted custom applications from view on the

screen.

Port Forwarding

Port Forwarding allows incoming traffic from the Internet to be forwarded to a particular computer

or device on your Wi-Fi network. Normally, the built-in firewall blocks incoming traffic from the

Internet. You use Port Forwarding to allow Internet users to access any server you are running on

your computer, such as a Web, FTP, or E-mail server.

For some online games, Port Forwarding must be used in order for the games to function correctly.

The use of Port Forwarding creates a security risk and should be turned off when not required.

NOTE

Some Mobile Wireless Networks provide you with an IP address on their own network rather than

an Internet IP address. In this case, Port Forwarding cannot be used because Internet users cannot

reach your IP address.

74

The Port Forwarding menu contains the following sections:

•

Default Applications

— Turn on each Port Forwarding application that needs to be able to

access the Internet by checking the box next to one or more applications.

•

Custom Applications

— You can define your own Port Forwarding applications, and then turn

them on or off as needed. To define an application, you need to know the outgoing ports

used by the application.

Default Applications

To turn on Port Forwarding Default Applications:

➊

Slide the Port Forwarding ON/OFF button to

ON

.

➋

Install the application on a computer connected to the 4G LTE Broadband Router with

Voice’s Wi-Fi network.

➌

On the computer, check its IP address for the Wi-Fi network. Alternatively, you can check the

computer’s IP address on the Connected Devices screen.

➍

Enter the computer’s IP Address in the Connected Device IP Address field beside the

application.

➎

Turn on this application by selecting its checkbox.

➏

Click

Save Changes

.

➐

On the Current Status screen, make a note of the Internet IP address of this device.

➑

Ask users on the Internet to connect to the Internet IP address of this device. These

connection requests will be forwarded to the IP address specified in step 3.

75

Custom Applications

Port Forwarding Custom Applications allow you to define your own applications. Once defined,

these applications can be turned on and off in the same way as pre-defined applications. To define

an application, you need to know the ports and protocol (TCP, UDP) used by the application for

incoming traffic.

To add/delete Port Forwarding Custom Applications:

➊

Click

Add a Custom Application

.

➋

Enter a suitable name for the application you are adding.

➌

Enter the beginning and end of the port range for each application. Each application has its

own port range.

•

For a single port, enter the port number in both the

Start Port

and

End Port

fields.

•

For a port range, enter the beginning of the range in the

Start Port

field and the end of

the range in the

End Port

field.

➍

For each port range, select the protocol (TCP or UDP) used by that port range from the

Protocol dropdown menu.

➎

Enter the IP address of the connected device which will receive this traffic.

➏

To remove a Port Filterting Custom Application, check the Delete checkbox for that

application.
