To keep this short, the seniors at the company I work at have set up a private VPN, on which you must connect in order to access different company resources. Everyone has their own profiles and secret pins they have to enter in order to connect to their VPN profile. The private company resources deny ALL IPs except for the VPN IP.
I really liked this setup from day 1 and I wanted to get to know how to set up a VPN like this on my own just to learn how to do it, maybe to use it on a side-project someday. Any resources you could point me to?
Thank you for your time!
