IPS analysis - Alarms
Support reference 85210
Packets that raise alarms occurring before the filter inspection or other alarms (notably ip:755 and icmp:112) would still pass through the firewall despite the presence of a filter rule configured to block the corresponding network traffic. This issue has been fixed.
Refer to the list of alarms occurring before the filter inspection in the Stormshield knowledge base (authentication required).
