If the VPN is not shutting down the sockets gracefully (which it sounds like
it is not), then the server would not be able to detect a lost client until
the OS times out internally (which takes a long time). That is why you need
to implement keep-alives in your packet traffic. That way, the server can
close the socket on its end if no packets have arrived from the client after
an idle period of time.

That is exactly what you need to do.
