I need a local repo solution for my redhat servers without internet connection. Is it possible?

Hello I have 3 RedHat 7.9 and redhat 8.7.5 servers in my environment. These servers are connected to our local network but not to the Internet. Can I set up an environment in my environment where there are copies of all the repos of Redhat that are open to the Internet and enable my servers that are not connected to the Internet to get updates from the environment where the copy repos I have installed when I say yum update or yum install in any application? So my server that is open to the Internet will be connected with Redhat ID, but my closed redhat servers will update or install from there. I hope I can explain what I need to research for such an installation, what is the keyword?

Thank you.
