I might have a problem. In my company we have a sealed network in within two SLES12-SP1 are planned to be installed. How can we register and update these two servers without connecting the sealed network to the internet? I have seen that a SMT server is available that manages the updates for the local network. But it seems that this server must be connected to the internet, too... together with the managed clients. But this will not be possible.

Does anyone know a good solution for my scenario?
