Should this add-on provide outbound connectivity - e.g. for SMB media

[a8ree]

I'd like to connect my HA instance to a cloud VM that has some storage. When connected to my tailscale network I am unable to ping or connect via SMB to other devices. Is this not supported or an issue with my config?

The current last release uses userspace networking (there is no tailscale0 interface to route traffic outward), so this is not possible.

Not using userspace networking is merged, but is not released due to a blockig issue: if you advertise the same subnets (eg. 192.168.1.x/24) on multiple machines (and there is a good chance that people we make this mistake), the HA instance will lose all it's network access (gets soft bricked). It's a known issue with Tailscale for years, no solution.

I don't now what is the plan to solve this, but I forked this add-on and made a workaround for this (adding local advertised subnets back to the routing table with higher priority than Tailscale's), you can install and use/test it form here: https://github.com/lmagyar/homeassistant-addon-tailscale

There is a PR to merge this solution to this "official" Tailscale add-on, but it is still open: #201

If you try my fork, add this to the config options:

userspace_networking: false

If you have any problems, please open an issue in my forked repo.

Thanks @lmagyar

I've installed your fork but not seeing any difference. I will ping you on your repo!
