Firewall Rules - Corega COR-WLBAR-AA User Manual

4-3 Firewall Rules

This allows users to configure the Stateful Packet Inspection Firewall to protect the user from external hackers. The firewall is enabled as default to provide the user with
the maximum protection. Most users should not have to make any changes to the firewall
The default settings of the firewall are as follows:
Incoming Data Always Block
Outgoing Data Always Allows
To change the Firewall, new rules can be created for both incoming and outgoing data flows. Use the Add, Edit, Move and Delete buttons to add new rules. Rules with a
higher number are processed before rules with a lower number. The default rule is always the last to be processed.
• Service Select from the drop down list the type of application to be covered by this rule. If a service is not listed, it can be created using Firewall Services in
section 4-4.
• Action Choose from the drop down menu of
BLOCK always
