I set this up a while ago, so the services are a little dated there might be something better.

I also use speedify, and I use 10, yes 10, different mullvad VPN connections.

I have three internet connections at home. Each of the three connections has a wire guard connection to my two closest mullvad cities and one connection across the Pacific.

Speedify sees the wireguard tunnels, and each of the three uplinks. And I can use that to aggregate all the different pathways and do a first pass the post race for every packet.

Every packet gets replicated 13 times, and it races across the ocean, and the first one there gets delivered to the destination.

It's great for gaming! I was able to shave off 65 milliseconds of latency to game servers across the ocean.

Is this wasteful? Absolutely, but it's fun! The reason I use 10 mullvad connections is just because you get 5 simultaneous logins per account.

There's a couple different ways to set this up, Linux network name spaces, really intricate wire guard configurations, VLANs. I went with VLANs, it was the most robust and portable across different devices.

Oh well, I had no idea that speedified now supports Open WRT directly. That's great

What's not great is the new router plan, three terabytes per month limitation, 5x the price of the individual plan...
