Connecting to VPN automatically
Solution 1:
No guarantees, but try a variation of this...
# drop into /etc/network/interfaces
# change eth0 if required
# change /path/to/protovpn.ovpn to the correct path and filename
auto eth0
iface eth0 dhcp
post-up openvpn /path/to/protonvpn.ovpn
# change wlpxxxx to the name of your wireless device
# change /path/to/protovpn.ovpn to the correct path and filename
auto wlpxxxx
iface wlpxxxx dhcp
post-up openvpn /path/to/protonvpn.ovpn
Then reboot.
