You'll need to import your V2Ray nodes to use. If you followed my guide for importing nodes from V2RayNG on Android, the process is the same.
The V2Ray node do not need to be fast, low latency or have access to your home network. The node is simply being used to access controlplane.tailscale.com and nothing more. For this requirement, you can basically use any nodes, even random free ones you found on the internet. Or use an "airport" subscription service, commonly used in China to fulfill this. You can also try my project insta-v2ray which uses free tunnel providers to provide to let you host V2Ray nodes on your own home network even if you're behind CG-NAT.
