I've uploaded all the files from the zip provided by cyberghost to etc/openvpn
Pasted /etc/openvpn/cyberghost.auth beside auth user pass and wrote my username and password in the box below it.
I did setup a network interface and forwarded connection from lan to vpn and wan.
Now when I start the vpn, it says started but my ip address is still not changed
Thank you so much, I checked my cyberghost account and somehow deleted the router by mistake, after creating a new config, everything is working perfectly now.
