How it works?

NetCom - this is rules-based packet filtering and routing software. When packet comes to program from network to TCP/IP stack or from TCP/IP stack to network:
If rules list is emty - packet sended to destination
       1. Packet checked by rule conditions.
       2. If all conditions of rule evaluates to TRUE - packet handled by rule actions, else packet pushed to the next rule.
       3. If no rules conditions evaluates to TRUE - packet dropped.
