[Resolved] clients don't realize that DDNS IP changed !

[oriuken]

I'm having a little issue here.
I have an OpenVPN server installed on an Ubuntu Server 12.04 and 3 other clients installed on windows machines.
My Server IP changes every 12 hours so I got a Dynamic DNS, and put it in the clients configuration file.

The clients config file is something like this:

client
remote xxxxx.dyndns.org
port 1194
proto udp
dev tun
dev-type tun
ns-cert-type server
reneg-sec 86400
auth-user-pass
auth-retry interact
comp-lzo yes
verb 3
...


Everything works fine, but every 12 hours when my Server IP changed and the DNS service updates the new IP, my clients seems to loose connectivity, because they still try to reach the old IP and not the new one...
Everything works fine if i restart each client connection, but there's not another way ?

Thanks for any tip
