Adding a New Filter

Defining Filter Rules

To add a new firewall filter, click the Add button to display the Add
a Filter dialog.
This dialog enables you to enter all the necessary information for
your filter.
You must enter a name for your filter in the Filter Name field, and
specify the Filter Action by selecting either Permit traffic or Block
traffic.
You can enter a Description for this new filter so that you can
quickly discover what it does.
You must define the Rules used by the filter. Rules include proto-
cols, ports, and source/destination addresses.
Important: Rules are applied from most specific to least specific.
For example, a rule to "permit TCP port 21" would be applied over
a rule to "block all TCP packets". For the firewall to function prop-
erly, the first rules written should block all inbound and outbound
traffic, then individual rules should be written to permit necessary
traffic.
