The Personal Firewall offers users the unique option to configure advanced rules that can override the rules automatically created by the firewall during normal user-firewall interaction. You may not realize it, but every time you allow or deny access to an application, you are creating a rule for that application. If you use Advanced Configuration to specify application access rights (such as scheduling and port rights), you are specifying parameters for the selected application, and thus creating an application rule. However, these rules are application-specific, so that if you create a schedule for an application, the schedule applies only to that application.
Advanced rules, on the other hand, are rules that you can create directly that affect all applications. If you create an advanced rule that blocks all traffic between 10 PM and 8 AM, the rule will override all other schedules and configurations that have been set for each application.
Rules in the Advanced Rules window will apply to all applications unless they are specifically tied to an individual application.
Sygate Personal Firewall is limited to a maximum of twenty Advanced Rules. That limitation is not present in Sygate Personal Firewall Pro.
