Using Neoware Firewall Defining Filter Rules You must define the Rules used by the filter. Rules include protocols, 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 properly, 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. 40 Configuring 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 spec-
ify the rule details.
