Yes, the default (--reneg-sec n) is 3600 seconds.

Yes, it does :) I hope to understand the TLS-handshake better now. After
(--reneg-sec n) 3600 seconds the Server tries to do a handshake with the
client. If the peer disappeared the (--tls-timeout n) Timer will try to
reach the peer every 2 seconds by default. After (--hand-window n) 60
seconds (default) the server tries to reconnect.

So it would be very fine when openvpn (in server mode) drops the connection
after the TLS handshake fails.

Thanks a lot !
