Port Filters
To set the port filters, click on the Port Filters link in the Current
Security Policies table. On the next screen, choose Add TCP or
UDP Filter or Add Raw IP Filter link depending on the type of
filter you want to create.
Add TCP or UDP Filter
Enter the criteria for the port filter into the table.
Ensure that the Protocol is appropriate for your interface.
Port filter default values for “allow” criteria will allow all traffic to
pass (as shown in this example).
Port filter default values for “block” criteria will block all traffic.
Filter criteria for source and destination ports define the range
within which traffic will be allowed/blocked by the filter.
Filter criteria for source and destination addresses and subnet
masks do not override port criteria, but add additional criteria for
the port filter.
Click on the Apply button to return to the list of defined port
filters.
To delete a port filter, click on the Delete button of the
corresponding row of the port filters table.
