Run Radmin VPN (and similar Windows client VPN) on Linux
Just for anyone considering using the VPN, be aware of their privacy policy Radmin VPN | Download Free VPN

It is true, but this is not VPN for browsing and such, but for making virtual LAN, thus you can either play or even do some IT stuff thanks to this program.
I know, this is not a perfect solution, but for those who are stack to Radmin, but they prefer the Linux, this is somewhat a resolution.
