Answer 3

Well, if it's software, then here: https://www.zerotier.com/ (Software-Defined Networking (SDN) software-defined network)
os-zerotier is a shareware virtual private network. Zerotier.com network controllers are used to connect devices. The free version allows you to connect up to 100 devices and an unlimited number of networks. On a windows machine there will be a client that will connect it to the server on which you define the network, set the addressing, generate keys, configure the firewall and much more there is a lot of everything.
Another option: ipfire ( https://www.ipfire.org/)put it on a virtual machine or on some machine, and then there are setup videos on the network (although not many) if you use openvpn, that is, on YouTube there is a video of networking step by step, and on setting up ipsec on their website ( https: // wiki.ipfire.org/configuration/services/ipsec).
