How to make domain authorization through vpn?

Question

VPN

Good evening everyone. This is the task set by the leadership. There is a head office and two branches in other cities of the republic. The head office has a domain network structure, authorization goes through CD. Now I would like the branches to also be in the domain and pass domain authorization through vpn. There is a nuance ip address received from the provider is dynamic, if I'm not mistaken, it is updated every 12 hours. I googled a little and found related questions, but I didn’t find an explicit solution, maybe you can show me where to dig here or tell me a little?

Answer 1

passed domain authorization through vpn

So does this VPN exist or not?
Buy a "white" IP address from the provider - what's the problem?

Answer 2

flies and cutlets separately! I'm talking about vpn and domain. in-place for the RODC domain. at least on the central server it is necessary to "raise" the realnik for vpn. and to knock on him even from where. Otherwise, you will have to use a linking service. what music gud!
