Hi, I have problem with VPN client. I read a post on this address http://forum.mikrotik.com/t/openvpn-key-file-from-linux-to-mikrotik/18270/1
Upload ca.crt, ca.key client.crt client.key to router. Import all of them. And now you can select client certificate in ovpn client configuration. It works for me.
My VPN provider offer only ca.crt, what can I do?
