OpenVPN Support Forum

I'm trying to set up a CyberGhost VPN on my ASUS RT-AC51U router.

I've followed the tutorials exactly (downloaded config files, uploaded openvpn, ca, crt and key files etc) but it's still not connecting. I'm getting the following error message:

rc_service: httpd 212:notify_rc restart_vpncall
openvpn[624]: Options error: Unrecognized option or missing parameter(s) in config.ovpn:23: ncp-disable (2.3.2)
openvpn[624]: Use --help for more information.

In terms of the OpenVPN file, it reads as follows:

client
remote [removed as I think this is sensitive info but its the server info]
dev tun
proto udp
auth-user-pass
resolv-retry infinite
redirect-gateway def1
persist-key
persist-tun
nobind
cipher AES-256-CBC
ncp-disable
auth SHA256
ping 5
ping-exit 60
ping-timer-rem
explicit-exit-notify 2
script-security 2
remote-cert-tls server
route-delay 5
verb 4

Can anybody help point me in the right direction to finding a solution? I can see it's possibly something to do with the 'ncp-disable' line but I'm not sure where to go from there?

Any help would be greatly appreciated! Thanks

Your router is a fossil and the version of openvpn it uses is not worth the electricity to run it.

That is why you cannot use --ncp-disable.
