I have 2 computers that are both inside NAT, where I do not want (preferable) to do port forwarding (or related things), however want to unite them with VPN to get access to private network. Let's call one computer "working station" and another "PLC forwarder". So, "working station" (client) connects to the "PLC forwarder" and can access it's private LAN network. My main purpose is to provide access to remote PLC controller that is on one LAN with "PLC forwarder". There is a good link that shows what I want to achive. It requires TeamViewer software that is quite expensive. It [TeamViewer] works fine as it moves traffic through their servers and I do not have a need to do router settings. And my questions are:
1) Do you know some service (for money is fine, unless too much) that can do same things - computer to computer VPN connection with proxying (thus I do not thoughts about static IP's or port forwarding - just some computer ID). I am sorry for asking this, as I googled proxy vpn or cloud vpn and got answers that are far distant from what I need.
2) I can set up any server software (ex. linux) on "PLC forwarder" as it's final aim to provide connection to PLC. May be you know some packets that are close to my needs. If yes, just name is fine.
Thank you for answers.
