I was looking for a similar thing in cloudflare: Exit Nodes (route all traffic) · Tailscale
I tried looking a few things in the dash but unable to find a way with which for instance If I’ve a cloudflare client running on android (warp or warp gateway) and I can select a another device (probably one with cloudflare tunnel daemon running) and then use this device as an exit node to my android device.
Not sure whether it is possible or not.
