[SOLVED]Problems to start openvpn on boot

[Elrondo46]

Hi,

I've a RPI 2 and I've some probs to start openvpn on boot, the network is not ready when it tries...
No problem with manual starting after boot.

I've tried to modifiy the service file with:

Requires, After, Wants.... network.target or network-online.target without success.

How can I solve it ?

Edit: Maintain config with network.target and change eth0 to static IP (no more DHCP)
