Thanks for the issue. There was the same issue with Debian 9.

Could you try this branch? https://github.com/Angristan/OpenVPN-install/blob/systemd-openvz-fix/openvpn-install.sh

Off topic, but the the link to the branch you posted, SOLVED ALL MY PROBLEMS! - I spent 6 hours on getting OpenVPN to work. You are my hero! :)

@michaelfresco Nice to hear, were you using OpenVZ?

@angristan Yes, I was using OpenVZ. All the time I could not get traffic through openvpn, even though I did successfully connect to it. It was a major headache honestly. I tried to ping 8.8.4.4, but got no relpy. The script from the systemmd-openvz branch fixed it all though! Real magic!

On Debian 9 the unit file openvpn-server@.service must use and modyfy for OpenVZ. The file openvpn@.service does not work.

Fix Problem running on OpenVZ angristan#584
309b19d 
On Debian 9 the copy of unit file `/etc/systemd/system/openvpn@.service` has no effect, see angristan#583.
Same problem as angristan#129 and angristan#378, unit can not start on OpenVZ. 

There must execute `systemctl enable` before `systemctl restart`.
So the new link to `/etc/systemd/system/openvpn@.service` was created before `systemctl restart`.
