Jun 29, 2017 at 16:18 comment added Adonist I checked the interfaces but it shows only the ip i'm pinging and the IP of the NAT. It doesn't show the IP before the NAT. Do I need any specific parameter ? I've used -vvvv to see the most information but still not.

Jun 29, 2017 at 16:13 comment added dirkt Yes, it's possible with tcpdump. Monitor both the incoming and the outgoing IF, and you should see the differents IPs. If there's a lot of other traffic at the same time which you can't stop, a better alternative is wireshark, because it has a GUI and filters.
