Ignored Ports Tab

IGNORED PORTS TAB
Web Filter detects network traffic through the driver and passes the information to the Web Filter service,
even though you may have chosen not to monitor certain protocols in the monitor settings. To improve the
performance of Web Filter, you can use the Ignored Ports tab to specify ports that you want the driver to
ignore. This will result in network traffic using those ports, not being passed to the Web Filter service.
Figure 9-7 Ignored Ports tab
Select one of the following options:
• Ignore traffic to or from these ports - This option will ignore all network traffic that use the ports in
the Ignored Ports list.
• Ignore traffic EXCEPT to or from these ports - Select this option if you want to ignore all network
traffic, apart from the specified port numbers in the Ignored Ports list.
Note: If you have enabled Protocol Signature Scanning, all network traffic will be scanned for
protocol signatures and if a signature is found, it will be used to determine whether the port is
ignored.
