Client or server?
The VPN icon on the desktop of NEO U9-H should lighten up when the VPN is connected to the server when you add a VPN option in 'Settings' > 'Device' > 'Network' > 'VPN'. (Rather than using VPN client)Client. I added the info in the network -> vpn menu but i'm not sure if it's working or not or if i input the right info that it asked for..
