I am doing some testing in the lab and came accross something that is interesting to me:
I enabled sigs 2000 and 2004 to test that the ips is inspecting the traffic and checked the action for those 2 sigs as producealert only. That worked well with informational alert sev. However, when raisng the sev to high the IPS starts blocking the icmp packets even though the action on the signature is only produce alert. Why is the IPS blocking such traffic? Am I missing something here. As always, help is appreciated.
