After I installed Endian Firewall. I enabled OpenVPN service and I want to connect to private network by OpenVPN Client. And this is workaround :
1. Download file cert.pem from OpenVPN Server. (System Admin can help you.)
2. Install OpenVPN Client.
|# sudo apt-get install openvpn
3. If you put your cert.pem on this path /home/your_account_name/openvpn-client/cert.pem when you connect by OpenVPN client you must use this command :
|# sudo openvpn –client –pull –comp-lzo –nobind –dev tap0 –ca /home/your_account_name/openvpn-client/cert.pem –auth-user-pass –remote Your_IP_Of_OpenVPN_Server
** This command has one line.
4. It’s complete.
