Port forwarding and setting up routes on windows?

Question

VPN

Situation: we have a friendly local network, a remote workplace and a mythical admin (churn!), so it is unlikely that I will access the network without perversions.
Next: you need to access the internal portal of the network mentioned above. Let's say I raise a VPN using TeamViewer VPN or Hamachi, and according to habrahabr.ru/qa/1352 I will create port forwarding on port 80 of the network's web server. And then I find it difficult to formulate an idea, because I don’t even know what to do so that when I access cp.portal.local from a browser on my machine, I get what I wanted. To register each time a route for the received remote IP? Edit every time hosts? Or do you need to “twist” something with the DNS?

Answer 1

Are you on this "friendly LAN" yourself or is it behind a router?

Answer 2

Do you have an external IP address from where you want to connect from? If yes, install OpenVPN on the remote workstation and your computer, on the remote computer, register OpenVPN in startup, configure it to connect to your remote workplace every time you start the computer (if it can’t, for example, you turned off the computer for the night, it will try to connect from time to time), and set up NAT in the standard way on the remote workstation.
DNS will rewrite OpenVPN for you, but even this is not necessary, because the IP addresses will be static. You will simply access the remote LAN just as if you were there.
If suddenly you have an external IP, but it is not static, you can use dyndns.

And how to organize access to 1C with a white IP and Windows 8.1?
