Set Up Port Filtering - SURFboard SBG6580 User Manual

Set Up Port Filtering

You can use Port filtering to define port filters to prevent all network devices from sending
outgoing TCP/UDP traffic to the WAN on specific IP ports. By specifying a starting and ending
port range, you can determine what TCP/UDP traffic is allowed out to the WAN on a per-port
basis.
Note: The specified port ranges are blocked for ALL computers, and this setting is not IP
address or MAC address specific. For example, if you wanted to block all computers on
your home network from accessing HTTP sites (or web surfing), you would create the
following port filter.
 Set Start Port to 80
 Set End Port to 80
 Set Protocol to TCP
 Select Enabled
To configure Port filters:
1. From the SBG6580 Web Manager, click Advanced on the SBG6580 Main Menu bar.
2. Click Port Filtering from the Advanced submenu options to open the Advanced Port
Filtering screen.
3. Enter the starting port number of the Port Filtering range in the Start Port field.
4. Enter the ending port number of the Port Filtering range in the End Port field.
5. Select TCP, UDP, or BOTH from the drop-down Protocol list.
6. Select Enabled to activate the selected IP port filters. Otherwise, leave unchecked.
7. Click Apply to create your port filters.
