    Hello.
    What kind of packets will fit these default rules in Jetico v1?:
    Code:
    Optimal Protecion -=> System Internet Zone -=> Accept Stateful UDP Inspection
    Optimal Protecion -=> System Internet Zone -=> Accept Stateful TCP Inspection
    I thought that stateful inspection is a way of firewall engine work.

    Hello P4z, Welcome to Wilders,

    These are the SPI rules. The firewalls that have SPI do have these rules, but they cannot be seen. In jetico all rules can be seen/edited, even the SPI.

    It means that if i set this rule as rejecting Jetico will act as nonstateful firewall?

    No, if you set that rule as "reject" it will block the returning packet.
