When a remote address disconnects, the behavior is somewhat different
depending on whether OpenVPN is running in TCP or UDP mode. In TCP mode
there is an explicit connection reset. In UDP mode, because UDP is
connectionless, the disconnection occurs due to a ping timeout, which can
be controlled by inactive or ping and ping-restart/ping-exit.
If you want to run custom code when a client disconnects, you might take a
look at the "client-disconnect" script directive.
