I set up Headscale and Tailscale using Docker on a VPS, which I want to use as my public IPv4 and Reverse Proxy to route incoming traffic to my local network and e. g. my home server. I also set up Tailscale using Docker on my home server and connected both to my Headscale server.
I am able to ping on Tailscale container from the other and vice versa and set up --advertise-routes=192.168.178.0/24 on my home server as well as --accept-routes on my VPS, but I can't ping local IP addresses from my VPS. What am I missing?
Both container are connected to the host network, I have opened UDP ports 41641 and 3478 on my VPS.
