Using Neoware Firewall
Defining Filter Rules 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.
To add a rule, click the Add button (in the Add a Filter dialog) to display the Add a Rule dialog.
In this dialog, enter a Rule Name, provide a Description, and specify the rule details.
