Hi Riccardo,
Welcome! Not off-topic at all.
Your config looks fine to my eyes; I don't think you _need_ different ports per endpoint, but I might be wrong.
With your tcpdump, if you can see incoming ICMP requests you should see outgoing ones too -- make sure they're not coming in on wg0 and going out on eth0; I've had that happen to me before. Can you send through the output of: `tcpdump -ni any icmp`?
