So I get a computer running this wireguard server and I can route all my traffic through my computer or does it use servers from a wireguard network?
Discussion
No, it’s entirely self hosted. WireGuard is native to the Linux kernel which is kind of awesome.
Unless you specify otherwise, your traffic to the internet goes out of the default gateway that whatever client machine was using before, eg your home router. But if you configure your client a certain way you can force all outbound traffic from that machine to go through another on your WireGuard network, making it similar to an exit node on a Tailscale network. There are tons of things you can do with WireGuard!
So I have to rent a server somewhere and I can run my home network and cellphone data through this server?
That’s definitely possible. I do that myself, renting a VPS from Linode that acts as my WireGuard server and the entry point to a VPN tunnel into my home network.
This is a great guide about how to set up a tunnel to your LND node but you can extend this to cover basically any service you host, not just a lightning node

I watched around 8 minutes of it and that seems like a great way to set up a VPN.
Since you make this one yourself would sites that block VPN ips block this?
No, they don't block it.
You use your own vps server with IP address which is not associated with IP addresses of known commercial VPN providers.
