Mikrotik

I wanted to use create a VPN back to my home network which I could use on the road. The idea was that I could interact with resources on my home network but also have a secure tunnel which I could use if I was needed to use an untrusted WiFi hotspot when in hotels, coffee shops etc. I had previously implemented OpenVPN to do this, with the VPN server running on a small linux machine inside my home network....

Like most people, my domestic ISP goes down sometimes. I work from home most of the time and the most common solution when this problem occurs is to ’tether’ a phone to use it’s 4G connection. This is OK, but a solution which allowed my entire home network to switch over to a backup internet connection would be much better… As well as my laptop maintaining a connection, movies could still be streamed (backup connection bandwith permitting) and IoT devices would keep working - you get the general idea....
