What’s your cellular signal like? I assume rather poor because it’s in the country.

Have you considered Starlink as a WAN source? Or is WAN sorted?

If WAN is fine and you just need to push traffic around site, Point to point or point to multipoint services are the best way. You’d need to consider things like PoE or midspan injectors for this to be viable of course so cable runs remain a topic to consider.

I’m not quite sure why everyone seems to be getting these types of 3rd party VPN services. What do you even need them for ? If you travel a lot and want to access content in other countries, sure why not, but if you’re just in your home I don’t see what meaningful benefit there is. You won’t suddenly get faster internet, it’s not inherently more secure and your IP is just your IP. I guess these companies it’s demographic are for people who don’t really know what they’re doing, kinda like Anti Virus software back in the day?
