  Select the 

Remember action

 option and select

 

Allow

 or 

Deny

 

to create a permanent rule for the 

communication. If a similar communication occurs in the future, it is automatically allowed or blocked. However, 
such rules are very general, since they would always allow all incoming and outgoing communications (for all 
target ports, all IP addresses...) for the given process. To specify more detailed parameters for a specified rule, 
click 

Show advanced options

. The figure below shows an example of limiting the HTTP communication (port 80) 

established by the Internet Explorer web browser. 

 

 

In addition to port 80 (HTTP), you may wish to allow communication on port 443 (HTTPS). There are three ways 
to accomplish this:

  o 

Wait until the web browser establishes communication on port 443 (e.g., when you log in to  your online 

banking account). You will be prompted to create an 

additional

 rule for the same application (Internet Explorer 

and the process iexplore.exe).

  o 

Click 

Custom rule

 to open a dialog window and specify detailed settings for the rule. You can add specific 

ports, IP addresses, IP address ranges, etc. In this case, all communication for the given application would be 
specified by only 

one

 rule.

1  If you want an application to behave differently within and outside the Trusted zone, or if you have different rules 

exclusively for incoming or outgoing communication (for the same application) more than one rule would be 

required.
