NetworkManager is a system network service that manages your network devices and connections, attempting to keep active network connectivity when available. It manages ethernet, Wi-Fi, mobile broadband (WWAN), and PPPoE devices, and provides VPN integration with a variety of different VPN services.
This package provides a VPN plugin for L2TP with optional IPsec support.
This allows me to connect to a L2TP VPN so I can work remotely. It integrates seamlessly with the network manager for an intuitive experience. However, I also had to install "network-manager-l2tp-gnome" in order for it to work properly.
