Again; I've done this, but now there's so many new things, I'm doing it again.
The truly new portions were...everything on the right side of this diagram;
The cloud needed a coax connector and a copper Ethernet connector. It's all easy to install, turn off the cloud (Weird), install the modules.
Getting the Cable section of Connections was an unusual struggle - The other drop down menu had nothing within. It required going into the Ethernet options and setting the Provider Network to 'cable', which is the next step AFTER the drop-downs.
The rest was typical DHCP and DNS setups, mainly on the Cisco server down there.
The post is rather short - How about adding a video to it?
Find out what A Record means - This site says 'Maps a name to an IP address', which is DNS. So it's another name for DNS? You can change them (presumably in a local context) to associate an IP address to another name.
