In this recording I am installing the IPFire router operating system into a Proxmox VE virtual machine. I will be using it to act as a router for the VPN connection, from the Windows 10 vm to the Centos 7 VPN server.

Go to Proxmox interface and select 'local' storage

Upload iso's and download templates

Go to VM´s 'Monitor' panel in the web interface.
