4.2.3.1 Rules setup

Rules setup allows you to view all rules applied on the traffic generated by individual applications within trusted zones

and the Internet. By default, rules are added automatically according to user reactions to a new communication. To

view more information about an application at the bottom of this window, click the name of the application.

At the beginning of each line corresponding to a rule, there is a button allowing you to expand/collapse (+/-) the

information. Click on the name of the application in the Application / Rule column to display information about the

rule at the bottom of this window. You can use the contextual menu to change the display mode. The contextual menu

can be also used for adding, editing and deleting rules.

Trusted zone in/out – Actions related to incoming or outgoing communication within the Trusted zone.

Internet in/out – Internet connection related actions to incoming or outgoing communication.

For each type (direction) of communication, you can select the following actions:

Allow – To allow communication.

Ask – You will be prompted to allow or deny each time communication is established.

Deny – To deny communication.

Specific – Cannot be classified with respect to the other actions. For example, if an IP address or port are allowed

through the Personal firewall, it cannot be classified with certainty, whether incoming or outgoing communications

of a related application are allowed.

When installing a new application which accesses the network or when modifying an existing connection (remote side,

port number, etc.), a new rule must be created. To edit an existing rule, verify that the Rules tab is selected and click

the Edit button.

4.2.3.2 Editing rules

Modification is required each time any of the monitored parameters are changed. In this case, the rule cannot fulfill the

conditions and the specified action cannot be applied. If parameters have changed, the given connection may be

refused, which can result in problems with operation of the application in question. An example is a change of network

address or port number for the remote side.

The upper part of the window contains three tabs:

General – Specify a rule name, the direction of the connection, the action, the protocol and the profile to which the

rule will apply.

Local – Displays information about the local side of the connection, including the number of the local port or port

range and the name of the communicating application.

Remote – This tab contains information about the remote port (port range). It also allows you to define a list of

1 2 ... 42 43 44 45 46 47 48 49 50 51 52 ... 123 124
