justine: A VPN is a private network that uses a public network (usually the Internet) to connect to devices with Private IP addresses from a machine on your LAN or from home. Instead of using a dedicated, real-world connection such as leased line, a VPN uses ‘virtual’ connections routed through the Internet from the company’s private network to the remote device. The VPN tunnel would be used for those who have a private IP address on their SIMs.

Virtual Private Networking tunnel
VPN is a Virtual Private Network over the Internet usually to connect a company server to a remote employees PC in the hope the content will be more secure.
They do have other uses though.
"Tunnel" is a bit of a buzzword at the moment for what is known in the trade as a time slot.
The Internet is used to connect to the ISP ( Internet Service Provider ) which then routes the connection to the VPN provider and that is the part of the connection usually referred to as a "tunnel";
A normal Internet connection is pretty secure anyway and using a VPN will use a few extra "hops" which will increase the ping, so in the real World such terms are just a sales pitch, as you can probably deduce from the link.

Virtual Private Network. It is a network from your device that "tunnels" (uses as a carrier) through the Internet to the server at the other end.
well there you are home. and you cannot make it to work. so you still want to connect your laptop just like you would when you sit at your desk at work. so the work router has a teleworker option. you set up a teleworker login. at home, you create a shortcut on your desktop, to a VPN (virtual tunnel) to your works Router (teleworker login). you are connected to the internet already. you click the shortcut. it opens the TUNNEL. it is as if you had a very long wire between your works router and your laptop. you are now logged in at work(via a VPN tunnel over the internet).
