Veeam has a free client backup app that you can point to a share.

Set throttling.

Ideally set it at your egress point so that sessions get throttled only when your max upload is reached.

If your switch plugs into a switch then they are in the same network (excluding L3 switches). Your devices will be sharing the 1gb link between switches but that’s not usually a problem for most home networks.

Have a core switch that everything plugs into.

Then here you go. Open your pocketbook.

Assuming you were on the same lan you could probably set up chat with HA. A game server likely has a lot of change in memory and keeping that synced would be possible but it might not be cheap.

Across a wan though is a different story and likely not reasonably possible.

Some devices will drop icmp packets. Does iperf show the same amount of loss?

Can you try a different internet connection such as mobile hotspot just to see if you have similar results? That could help identify it as a vps issue.

What’s your mtu inside the vpn?

What iperf speeds are you getting with UDP?

On windows you can use the test-connection -MTUSize powershell command to figure out the correct mtu.

If your udp speeds are normal but your tcp speeds are not, it could be fragmentation, or out of order packets, or high latency.

Without knowing much about, yes unless all servers are using tailscale. It’s simple to share hosts across tailscale tenants.

That’s getting more technical than what OP is doing though.

Thanks, you’re right

Rpi3 is pretty slow but you’re right it’s ok for testing.

Jellyfin doesn’t pretend to do external access well. Some people put a proxy in front of it, others do something like Tailscale to create a private network over vpn. Then you set up the Tailscale app on your mobile devices and it should activate for specific ip addresses or dns names.

I think even the igpu on that p320 would do what you need.

When they are streaming is it transcoding?

If not, it should be reducing the stream quality to adjust to the available bandwidth.

If it is, it could be limited to your pc’s available resources. You may want to turn on hardware transcoding.

Jellyfin has logs that will tell you if its transcoding and how well it’s working.

Tailscale does add additional hops to their route and has bandwidth limitations but it should be fine for streaming.

Physical diagram shows the actual physical connections between devices.

A logical would show separate VMs and containers and virtual switches and how they connect to each other.

Diagrams do change but are helpful to understand your infrastructure

Can you create both a physical diagram and a logical diagram?

Host your secure mail gateway on a service that lets you manage the ptr records. Alternatively outsource the SEG completely.

Reolink includes a cloud service but it’s not required. They do save video locally on camera, but you connect the camera and mobile app to their cloud service for authentication , config, and viewing.
