Here, Change the Remote IP Address According to Your MikroTik WAN IP.

• Now copy and paste your exported CA and Client certificate files that you simply saved in your Desktop by dragging and dropping from MikroTik File List, during this location and rename CA file as ca.crt, client certificate file as client.crt, and key file as client.key because we've used these names in our configuration file.
• Create another file named secret (because we have put the auth-user-pass file is secret) without any extension and put OpenVPN PPP username at first line and password in the second line and then save this file.
• Now run OpenVPN client software.
• Click the mouse right button on this icon and then click the Connect option. The OpenVPN Connection window will appear and it will ask to put your client certificate password that you have entered at the time of client certificate exportation.
