UTM 220 - Ping Dropped on the Firewall Live Log

Hi,
I have a problem with the UTM 220. When I ping the external (Internet sites) or to certain devices that are in my same network and the same network of UTM, Firewall Log I Live in the package "ping" is Dropped dall'UTM. I also added a Firewall rule that allows the ping does not work. Same problem with traceroute.

Can you help me identify the problem?

Thanks and Regards

Dario
