The Networking Setup
This was one of the simplest parts of the setup for me having a background in telecommunications and engineering. I went with a Teltonika RUT950 which I’ve used in other projects. It’s a small 12v industrial router which supports multiple WAN connections (physical ethernet, WiFi and GSM) as well as sophisticated firewall and routing configurations.
The primary connection is via WiFi to the NBN radio link in the house. The secondary connection is a 4G connection to a fixed IP Optus plan via a high gain antenna. The NBN connection is generally quite good, but it fails often enough that having a backup is fairly cheap insurance. I use a dynamic DNS service to provide connections into the setup via the web as well as TeamViewer for direct PC control. I also have a standard wifi hotspot for a Nest camera and convenience while working in the dome.
If I did it again I wouldn’t change a thing.
