WORKING WITH FIREWALL RULES
The Firewall operates on the basis of two types of rules:
Packet rules. They are used for posing restrictions on packets regardless of the application. Typically, such
rules restrict incoming network activity on specified TCP and UDP ports and filter ICMP messages.
Application rules. They are used to set limits on network activity of a specified application. Such rules allow finetuning the activity filtering, for example, when a certain type of network connections is banned for some
applications but is allowed for others.
