Help setting up a cyberghost openvpn

Hi everybody,

For a few days, I’m trying to configure an openvpn interface on a RB2011.

I’m a customer of Cyberghost who gives me several files :

  • ca.crt


  • client.crt


  • client.key


  • openvpn.ovpn

Here is the content of the last file :

client
remote 97-1-ad.cg-dialup.net 443
dev tun 
proto tcp
auth-user-pass


resolv-retry infinite 
redirect-gateway def1
persist-key
persist-tun
nobind
cipher AES-128-GCM
ncp-ciphers AES-128-GCM:AES-128-CBC:AES-256-GCM:AES-256-CBC
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


ca ca.crt

cert client.crt

key client.key

I followed a guide (found on this forum) that suggests combining the client.crt and client.key files into a .pem file before import it allong with the ca.crt in the router.
Then creating a ppp profile and a OVPN client.

I tried multiple combinations of parameters on the client (Auth, Cipher,…) but the connection does not want to be made. Logs says :

10:01:54 ovpn,debug openvpncyberghost: disconnected <unsupported auth digest>

Could someone tell me more?

OpenVPN in RouterOS is limited, half-finished, or whatever would be the best description. If nothing else, “auth SHA256” is one of missing things.
