Port Filtering

The Port Filtering page allows you to configure port filters in order to block Internet traffic

to specific ports on all devices on your LAN.

Similarly, you can prevent PCs from sending outgoing TCP/UDP traffic to the Internet

from specific IP port numbers. This can be configured using the Port Filtering page.

To access the

Port Filtering

page:

1

Click the

Router

menu tab.

2

Then click the

Advanced/Port Filtering

submenu.

Port Forwarding

The Port Forwarding page allows you to run a publicly accessible server from your LAN

by specifying the mapping of TCP/UDP ports to a local PC. It allows incoming requests to

specific port numbers to reach a web server, FTP server, mail server, etc.

To access the

Port Forwarding

page,

1

Click the

Router

menu tab.

2

Then click the

Advanced/Forwarding

submenu.

To activate the port forwarding:

1

Enter the port range of the Internet traffic that you want to forward, and the IP

address of the server to which you want to forward that traffic. If you enter no

External device on the public internet; doing so will grant access to those devices

only.

2

Select the protocol(s) to be forwarded.

3

Enter the Description name.

Description

Local IP

Address

Enter the IP address to which forwarded traffic should be sent.

Enter the range of port numbers (start and end port) to forward. If

only a single port is desired, enter the same port number in the

Start

and

End

locations.

Start/End Port

You may optionally enter Addresses of External devices on the

public internet; doing so will grant access to those devices only. If

you enter no External device Addresses, any device on the public

Internet may access your devices.

External IP

Enter the range of port numbers (start and end port). If only a single

port is desired, enter the same port number in the

Start

and

End

locations.

Enable

Select ON or OFF to enable Port Forwarding rule.

Note:

You may need to assign static IP addresses to devices on your LAN to insure that

the port forwarding you have set up will always apply to them.

Port Triggers

The Port Triggers page allows you to configure dynamic triggers to specific devices on

the LAN. This allows for special applications that require specific port numbers with

bi-directional traffic to function properly. Applications such as video conferencing, voice,

gaming, and some messaging program features may require these special settings.

Port Triggers are similar to Port Forwarding except that they are not static ports held

open all the time. With the port triggering function, the Cable Modem/Router detects

outgoing data on a specific IP port number and opens corresponding target ports for

incoming data. If no outgoing traffic is detected on the Trigger Range ports for 10

minutes, the Target Range ports will close.
