- [X] ACLs
- [X] Support for alternative IP ranges in the tailnets (default Tailscale's 100.64.0.0/10)
- [X] DNS (passing DNS servers to nodes)
- [ ] Share nodes between ~~users~~ namespaces
- [X] Share nodes between ~~users~~ namespaces
- [ ] MagicDNS / Smart DNS
## Roadmap 🤷
We are now focusing on adding integration tests with the official clients.
Suggestions/PRs welcomed!
