The packet filter allows for definition of advanced rules for specific network communication. Besides selection of a local application and traffic direction, protocol, remote IP addresses, remote and local ports and other parameters can be defined.
Rules for packet filter can be defined as follows:
By hand — click on the button in the Applications tab of the Network Security section to open the Advanced Packet Filter dialog where packet filter rules can be viewed, edited and removed (for details see below).
Automatically — the Connection Alert dialog is opened when a connection which does not meet any rule is detected (see chapter 5.2. Connection Alert (unknown traffic detection)); if the Create an advanced filter rule option is checked, a packet filter rule will be created instead of a standard rule.
Note: Advanced packet filter does not distinguish between trusted area and the Internet (an IP address, subnet, IP group, etc. are always specified in the rule). ).
