several tun created for a single openvpn-client connection under raspbian stretch

[boistordu]

Hi,

I have noticed that by doing

Code: Select all

systemctl enable openvpn-client@conffile

under raspbian to have a client connection at boot, from time to time there are several connection made and so several tun interface created. Also the case if restarting every x hours with systemctl, doesn't close tun0 for example and creates tun1.
So is it a bug?
Does raspbian coders have screwed the code?

Thanks in advance
