NetBird zero-traffic groups and policies: LAN access without opening ports
aestheticedwar1 · x · 2026-10-20
The author shares NetBird's access control docs and a detailed groups-and-policies guide: one group plus one policy decides who reaches the server, no ports opened, and everything runs encrypted over WireGuard. Doc highlights: - Deny-by-default zero trust: no peer-to-peer traffic without an explicit policy; - Least-privilege grants tied to identity and device posture checks; - The auto-created Default all-to-all policy undermines zero trust and should be replaced; - New Control Center offers an interactive graph of peers, groups, and policies.
