I am trying to connect to a VPN server through various VPN tunneling protocols ( OpenVPN & PPTP ). My choice is to use the libnm-glib-dev library to establish the connection. Is there any pointers/quick guide to create a tunnel through libnm-glib-dev library? ( I hope libnm-glib-vpn library for creating plugin only ).
Your help is most appreciated on this.
