I've faced the same problem as some people here: I am unable to access any Docker container running on br0 with a static address set. I've tested different commands, such as:
tailscale up --advertise-routes=192.168.1.0/24 --accept-routes --accept-dns --advertise-exit-node
tailscale up --advertise-routes=192.168.1.0/24 --accept-routes=false --accept-dns=false --advertise-exit-node
Basically, I don't want my home server to be an exit node, so I would remove it later.
However, regardless of whether it's included or not, I can't access anything from Unraid Docker. I can access Unraid itself and other IPs running on my network, like Unifi, Printer GUI, etc.
Is it possible that some routes need to be added to the routing tables?
