Most likely you are under CGNAT, so your best bet is Tailscale, Wireguard, CloudFlare Tunnel or Zero Tier. Pick your poison.

Another piece of the puzzle is probably your WiFi router, as you normally won’t get speeds near 1Gbps over WiFi. In order to benefit maximally from it, you need to connect your devices (laptops, stationary PC, TV, etc.) with a cable to get the most of it.

You should also try to disable some pfSense plugins, like OpenVPN, zenArmor, etc. as they will severely limit your bandwidth throughput. But as others said, most likely you will also need to upgrade your hardware box, and you can migrate to OPNsense while at it.

Just changing the SSH port to non standard port would greatly reduce that risk. Disable root login and password login, use VLANs and containers whenever possible, update your services regularly and you will be mostly fine

If you are behind CGNAT and use some tunnel (Wireguard, Tailscale, etc.) to access your services which are running on Docker containers, the attack vector is almost not existing.

Do you really need multiple VMs, can’t you run all at one? The easiest would be to install some windows/Linux on a single machine. Then stream your games with Sunshine/Moonshine and connect over RDP/VPN?

I am very much interested

The reality is that you won’t learn much just by reading, you need to try to debug stuff and eventually work in the area to truly learn.

But I am sure there are plenty of tutorials and video courses in various platforms where you can learn a bit on the topic. Coursera might be a good place to start as you can enroll for free to those courses if I am not wrong.

You can also try rsync/rclone too and see how they perform.

Sorry in that case I would recommend you do iperf and see what the traffic would be. Make sure you whitelist the traffic as well.

Try to execute

ping -c 1000 1.1.1.1

And check for any packet loss and jitter.

Additionally I would also recommend trying a different test server and comparing the results.

Keep in mind that your ISP might also have issues with the connectivity which can be fixed in the following days.

If you ask me, Unraid went the Plex way, enshittification ensues.

Yes, here the question is if you really need to upgrade to 5, and if you really need, why not buy a dedicated NUC for example that would be a lot more powerful and extensible than the 5, while also consuming not too much more power.

Sorry, HA is Home Assistant, not high availability.

You stated that you are a Dev yourself, but then I was expecting that you should have tried to check their API and make the calls with curl, Postman, Insomnia or whatever, but apparently you never tried.

Perhaps the problem was in the third party plugin you were using from the beginning and they cannot really be responsible for that.

I am pretty sure they have monitoring on their API backend and can spot a problem, as I seriously doubt that if the problem was with their API you would be the only one experiencing those problems.

Thanks a lot for the link, will check it out.

I think the problem is that ZFS expects zvols and qcow2 is adding an additional layer on top and this is increasing the wear and tear of the disks especially SSDs and eventually it is not recommended. Plus qcow2 I think is better for virtualisation.

Exactly my point

Unraid is also based on Linux but it is a lot more user friendly

Or Unraid if you are willing to pay their price, since Unraid is more suitable for Linux newbie.

Try with dig to check what DNS you are using. And check if you have support for both IPv4 and IPv6.
