There are two completely different things called VPNs:
- The server running in the office allows you to connect to the computer via the Internet from any place in the world where there is an Internet connection.
- A dedicated system that allows you to connect to the server and then forward the connection to its Internet connection.
Either way will make your device look as if it is somewhere else, but it can’t be “anywhere”, but just where both are connected to the Internet.
As for connecting your wifi? maybe not. Your router must be connected to a modem (if you don’t have a modem under the same circumstances), and the router is connected to your Internet provider via a telephone line or cable-that is your “location” on the Internet.
You can connect the phone to a Type 2 VPN. You can connect your desktop to a Type 2 VPN. But it will be difficult to connect your wifi router to it.
Since Type 1 VPN will only show you a few miles of your location (and if your office uses the same provider as you, then it will show that you are in the “same” “location”), then it will not even show you You can connect the router to the router, or you can use the router (this type of VPN will still disconnect you).
If you want to “hide”, find SSL VPN. Then run Tor on your device to connect to the VPN. This is not perfect, but it will make it harder for someone to find your location. (Unless it is your government, it is trivial for them to find out.) To know if this applicable to your current VPN provider, check it at the review portal Top50vpn.com.
Of course, running Wifi will blow the whole idea. Anyone using Wireshark can see what you are doing (the program is free).
Is it possible to connect the device directly to WiFi anywhere in the world? Then the answer is no. The WiFi range is usually less than 100 meters.
Connect to your home network, which can include WiFi and Ethernet-connected devices? The answer is yes. There are constraints. Every different device on the home network you obviously want to access must be turned on and working properly. It must also be accessed through a unique port number on the Internet. You cannot use IP addresses on devices on your home network over the Internet. You must open a connection to the home’s public IP address, and then select a specific device through the port specifically assigned to access the device.
For example, my home security cameras each have a static IP address on my home network. The cameras can be connected to the network using Ethernet or WiFi, and each camera is configured with its own specific port number. These ports are forwarded from the Internet to the specific internal IP address of the corresponding camera through my router. If you can access the Internet, you can use the appropriate port number to select a specific camera and observe what is happening in front of that camera. I can also pan and tilt each camera to view the corresponding room.
If you have a dynamic (changing) public IP address from your ISP, you will need to use the DDNS service to access the public IP address of your home. My specific camera manufacturer provides DDNS services for use with its products, but some free or paid services also work well.
