Apologies, I have totally confused things due to a lack of clarity. A VPN does not work, as noted above VPN connections are blocked. To clarify, I currently have my desktop connected to the router. Separate laptops are connect by WiFi to their own dongle, which then connects to the internet via the mobile network. I am trying to replace at least one if eventually not all of the laptops with virtual machine for convenience and space saving. I have set up the first VM which is working great but connecting through the router so using the same IP address as my desktop. I just need to get it to connect to the dongle which does not even need to be plugged in. I think that all I need to do is connect the dongle to the WiFi adaptor on my desktop and get the VM to only use the WiFi adaptor, but I cannot see how to do this. Hope this helps.
