I want to setup a VPN (or proxy) server on my workstation located outside my permanent residence and behind NAT. I need to use workstation's network IP. The problem is I don't have physical nor admin access to the router, so I cannot setup NAT traversal accordingly. Is there any non-corporate simple-to-use software/service that would allow me to bypass NAT?
I thought of TeamViewer example. As far as I know TeamViewer uses 3-way communication using their server-side in order to connect machines and bypass NAT. Are there any services out there providing similar access but for VPN functionality? Or how do you configure such server by yourself, so a remote VPN server behind NAT could ping it and therefore allow other machine to establish VPN connection? Or do you know of any other solutions that would solve this problem? Appreciate for any recommendations in advance.
