It's impossible to use HE.NET tunnel iface as a parent for OpenVPN instances
- HE.NET tunnel iface [for example, WAN_HE]
- Create an IPv6 OpenVPN instance on parent iface WAN_HE [for example, OVPN_AMS]
- Go to dashboard. OVPN_AMS is down.
- OVPN_AMS is up
- "Status -> System Logs -> OpenVPN" has a string "Options error: --local and --nobind don't make sense when used together"
- Edit /var/etc/openvpn/client?.ovpn file by removing nobind option
- Restart openvpn service
