The purpose of this FAQ is to provide a realistic launch pad for new users of Tiny and Kerio Personal Firewalls, as well as to serve as a reference for experienced users. This isn't documentation. It's basic firewalling with these firewalls. It covers getting started and having a sound basic set of firewall rules that can be developed as unique needs and new considerations evolve.

The default behavior is to deny anything not explicitly allowed or denied by a rule. Therefore, we will begin by discussing making the rules that are needed to allow normal traffic to be permitted.

The firewall processes the rules from the top down, and, when it encounters a rule that can be applied to a specific type of traffic, it applies the rule and stops processing rules. No rule below it will be considered. This cascading can be used to create conditionals by grouping rules but confuses many new users. Rules can be moved up and down in the processing sequence using the arrow buttons to the immediate right of the firewall rules table in the administrative interface.
