My case is this:
1. The user is connected to public Wi-Fi
2. a new session is created and the server knows from which remoteIp
3. after 15 minutes, as the User works with the open session, the Wi-Fi signal is lost and automatically connects to a mobile network on his phone
4. The session has not timed out and the session has not been terminated, but the user's IP address has already changed.
I need to know when point 4 happens, is this possible?
I try via TUn
