Hey guys, I´m Back
I got the solution to this case.
The problem was the reply and icmp session.
I did the comand "set security flow sync-icmp-session" because this command do not inspection the reply, when I start the ping from Lan (trust), the reply is coming in the same session and I configured the icmp-request to drop all connections from internet.
With the session opened the reply will not dropped
The secret was the command to allow the icmp inspection and drop the ICMP-Request in the term 4
Tks for everyone that helped me
