I'm currently using CF Tunnels and I'm thinking about this (I have pretty good offers for VPS as low as $4 a month)
Can you comment on bandwidth expectations? My concern is that I also tunnel Nextcloud and my offsite backups and I may exceed the VPS bandwidth restrictions.
BTW I'm testing Pangolin which looks AWESOME so far.
Because carriers are smart and greedy and lobbied the government to sell a block of spectrum that is only used in the US for 5g, so if you want good connectivity in the us, you have to buy a phone from them at 3 times the price.
You already have a lot of good answers ... but I got one more to add.
I have a very similar setup on my homelab and I'm using a Cloudflare tunnel.
It's a free service and it's really good because it allows you to expose web services and specific ports for remote access over dynamic IPs without having to expose your own router.
Cybersecurity engineer here: I work for a defense company's data protection arm and you have NO IDEA how true this is. The really good companies spend almost as much in employee training as they do in software/hardware.
But you wanna know what's even a bigger problem than human stupidity? GREED I'd say about 50% of the companies out there have very little or no security because why invest in something that produces no profits?
They have an external connector in the back for adding external batteries and the menu to do so is analog.
I added a golf cart battery to mine tripping the capacity for very very cheap.
Look in the used market.
If you want something better, Eaton is the go to, look for used deals in marketplace / craigslist. I found someone selling Used industrial Eaton UPSs with extended batteries for 150$ the set
WOW! That's one hell of a deal. You've convinced me XD I'm installing pangolin Right now. The hell with Cloudflare and their evil ways
