I enabled an openvpn globally by

systemctl enable openvpn@con.service

Which works well and I'm connected to my VPN after reboot. But once I suspend my laptop instead of rebooting, or simply lose the connection, I can't access to internet any more and have to do either a reboot or a systemctl restart openvpn@con.service

How can I reconnect automatically to my VPN?

An idea I have is to edit the openvpn@con.service manually and set a Restart=always and a RestartSec=15. But is that safe any longer? Won't my connection be interrupted? Is there a better solution?

This is what my con.conf looks like:

dev tun0
proto udp
remote pw.openvpn.ipredator.se 1194
resolv-retry infinite

auth-user-pass /etc/openvpn/IPredator.auth
auth-retry nointeract

ca [inline]

tls-auth [inline]
ns-cert-type server

keepalive 10 30
cipher AES-256-CBC
tun-mtu 1500
verb 3

    Odd that config is having OpenVPN exit. Could you check your log files (e.g., /var/log/daemon.log, /var/log/syslog, or /var/log/messages) and see if it gives a reason why? It should be logging a fair bit with verb 3.

  • Odd. Wonder where your syslog is going. Which distro is this?

  • It's arch. I think journalctl should do this? nopaste.info/e0204b6c88.html Aug 22, 2013 at 16:15
  • That looks like it could be a syslog. But I don't see any OpenVPN stuff in there.

You can configure OpenVPN not to exit when the connection goes down, and instead to reconnect (e.g., ping-restart instead of ping-exit). Also make sure you don't have things like inactive (exit on inactivity), or single-session.

You can also configure OpenVPN to keep the tunnel around, so traffic will potentially be sent insecurely with persist-tun. In addition, you may want to add firewall rules to ensure your traffic doesn't leak.

BTW: If you add the firewall rules, then you can safely have the connection interrupted.

    Thanks, these are great ideas. Can you be a bit more detailed and teach me how to do so? I added my .conf file to the start-post. Aug 22, 2013 at 15:33
  • No this will not work if the client ip changes, openvpn service will return "AUTH_FAILED" and just give up... keepalive and ping-restart does not have any effect over this unfortunelly... Nov 23, 2017 at 18:32
