On my firewall shows : Firewall has blocked 57 intrusion so far. But when I click the link (on “57”) which open the log viewer, there are no items to show.
Is this a bug or the intrusion can’t be logged or what?
Blocked firewall events will not be logged unless specifically instructed to do so.
I don’t know what firewall policy you are running under; “stealth”, etc. However, in your global firewall rules there should be one rule at least that blocks all unknown inbound traffic. If running in Stealth mode, that rule will be the last global rule. Logging should be enabled on that rule by default. If it is not, you will have to manually set it on as shown in my attached screen shots.
If logging is enabled on the last global rule, then some other firewall block rule is generating your alerts. You will will manually have to set on logging for each blocked rule until you find the rule generating the alert.
