What is the VPN app?
If you want to reach files on your company's servers, you may need a VPN (virtual private network). A VPN lets you log in to a private network through its firewall, for example from a public location or from home. Check with your system administrator whether you need one.
The VPN app stores your VPN connections as profiles. You can import a profile from a file or add one manually.
The connection types include WireGuard, OpenVPN, OpenConnect (AnyConnect), and L2TP/IPsec. Some devices also offer others, such as Cisco IPsec and PPTP.
Checked against the LuneOS code and installed apps. Nobody has tried these steps by hand yet, so tell us if something differs.
