Field Description
Inactivity Time
60 minutes [Factory default when a user is created. Otherwise, it is 0 (zero)].
Enter the amount of time during a user session where there is no Internet access activity,
indicating that the user is no longer online. If the inactivity timer is triggered, the user
session will be closed automatically. In order to regain Internet access, the user must log in
again with their User Name and Password.
Note:
Set the Inactivity time value to 0 (zero) to prevent session timeout.

Overview
Most well-known Internet applications are supported by Application Layer
Gateways (ALGs). ALGs automatically adjust the gateway firewall to allow data to
pass without making any custom settings. We recommend that you test your
application before making changes in this section.
Applications & Gaming > Port Filtering
Use this window to configure transmission control protocol (TCP) and user
datagram protocol (UDP) port filters. These filters prevent a range of TCP/UDP
ports from accessing the Internet. You can also prevent PCs from sending outgoing
TCP/UDP traffic to the WAN on specific IP port numbers. This filter is not IP
address- or MAC address- specific. The system blocks the specified port ranges for
all PCs.
Select the
Port Filtering
tab to open the Applications & Gaming Port Filtering page.
Applications and Gaming Port Filtering Page Description
Use the descriptions and instructions in the following table to configure the port
filtering for applications and gaming features used on your residential gateway.
Click the
Enable
checkbox to enable port forwarding for the relevant application.

Port Filtering
Start Port:
This is the beginning of the port range. Enter the beginning of the
range of port numbers (external ports) used by the server or Internet
application. Check with the software documentation of the Internet
application for more information if necessary.
End Port:
This is the end of the port range. Enter the end of the range of port
numbers (external ports) used by the server or Internet application.
Check with the software documentation of the Internet application
for more information if necessary.

Enable:
Check this box to enable filtering on the specified ports.
Applications & Gaming > Port Range Forwarding
Important:
The gateway normally implements a feature called Port Translation. Port
Translation monitors what ports are actually being used by your PCs or other
devices on your LAN. This monitoring provides an added level of security beyond
what the firewall provides. However, there are some applications that require the
gateway to use specific ports to connect over the Internet.
Use Port Range Forwarding to forward ports from the public Internet to specific IP
addresses in your local network. Select the
Port Range Forwarding
tab to open the
Applications & Gaming Port Range Forwarding page.
For the Start and End Port, select a port from the recommended 49152 - 65535 range.
Keep in mind that ports used are program specific so check which ones the program
requires to be forwarded. Type the port number or range in both boxes. In the IP
Address box type the name of the computer’s IP address to which t
his is to apply.
Note:
Port Range Forwarding continually exposes the selected ports to the public
Internet. This means that the gateway’s firewall is no longer active on these ports.
The device with the forwarding IP address can be exposed to hacker attacks while
the port range is being forwarded.
