Blocked traffic not logged - Bug

lferrara

Today,


one of my external connection was not working, so I decided to have a look at Security Logs to see which port this application uses.

Blocked traffic is not logged. I filtered by destination IP (because I know the IP), but nothing appears. No filter, same result.

So to know which port was used, I created a Policy rule allowing ALL and then I was able to find the destination port.

This is a bug. Can someone do this test?

    Hello everyone. Just started testing XG Firewall SFOS 17.0.6 MR-6 and I can confirm that in 2018 the symptoms persist.

    It would be great if a Sophos engineer could explain this behavior: all blocket outbound traffic from LAN to ANY is indeed blocked by default but it is not logged anywhere.

    By adding at the bottom a "DENY ALL THE REST" rule, I could capture the dropped packets. A in-deep explanation about the firewall chains would be welcome.

    Could this be corrected with a minor release?

    Hey  

    Traffic not matching any existing firewall rules are dropped under firewall rule 0 in the logs. Please take a look at this KB article for further explanation.

    Best,
