I mostly just want to log connections and IPs to have a record of things.

I just use Firefox Sync. Works on all those platforms.

Yea, I didn’t like that they are going to drop support in the next version or whatever. Not sure if it’s their intended replacement, but Wireguard is installed by default in TrueNAS Bluefin. I recently switched to that, and I find the performance is way better than OpenVPN.

What are you using to monitor wireguard?

You’d set your firewall rules to only accept requests from the cloudflare datacenter IPs for those port forwards. So, the ports would be otherwise blocked to anyone else trying to access them directly.

I have one of these mini PCs arriving soon. A little more money than I wanted to spend and no idea if this brand is any good. But it checks a lot of boxes for a backup server project I’m working on - eMMC for boot, microsd slot, M.2 2280 NVME socket, and a 2.5" SATA connection. They have some other variants as well that don’t cost as much.

I originally got a used Dell Optiplex Micro from eBay for this. They come with a 2.5" SATA connection. But I learned the hard way that not all models come with M.2.
