I read online that there is such thing as DoubleVPN what basically means
PC -> vpn1 -> vpn2 -> internet
However, its stated here: https://www.bestvpn.com/privacy-news/chaining-vpn-servers-double-vpn/
That it can be done with vpn providers who support such vpn chaining "Double-hop VPN services". They said another way to do the vpn chaining yourself would be with virtual machine. Basically having one VPN client running as you would and then creating an virtual machine and running another VPN client in it and doing your things on that virtual machine. In short:
PC -> VPN 1 -> Virtual Machine -> VPN 2 -> Internet
I have very little knowledge of how vpn works in general and trying to find a way around of learning everything by making a post here.
The first question would be if this really works and is safe method?
Thomas Pornin answer from this post: Connect through two VPN clients
states (in short) that:
Don't do it, simply brings more problems.
However difference here is that the OP there did not use virtual machine.
Secound question would be, if it is working and is safe after all, could it be possible to avoid virtual machine between and just use OpenVPN for example to do the job on one os?
