* [management] Require a private proxy cluster for cluster and direct upstream targets
Cluster targets and direct upstream targets make the proxy dial the
upstream from its own host network instead of through the embedded
NetBird client. Only clusters running in private mode are meant to do
that, but the service API accepted these targets on any cluster.
Service create and update now reject such targets unless the service's
proxy cluster reports the private capability. An unreported capability
is treated as unsupported.
* [management] Require every proxy in the cluster to be private
The private capability is aggregated as any-true, so a cluster where
only one proxy runs in private mode passed the check. The mapping is
delivered to every proxy in the cluster, so the non-private ones would
serve cluster and direct upstream targets from their host network too.
Validate these targets against a unanimous aggregation instead. The
existing any-true lookup stays as is for the dashboard flags and the
agent network gateway.

Adds a new "private" service mode for the reverse proxy: services reachable exclusively over the embedded WireGuard tunnel, gated by per-peer group membership instead of operator auth schemes.
Wire contract
- ProxyMapping.private (field 13): the proxy MUST call ValidateTunnelPeer and fail closed; operator schemes are bypassed.
- ProxyCapabilities.private (4) + supports_private_service (5): capability gate. Management never streams private mappings to proxies that don't claim the capability; the broadcast path applies the same filter via filterMappingsForProxy.
- ValidateTunnelPeer RPC: resolves an inbound tunnel IP to a peer, checks the peer's groups against service.AccessGroups, and mints a session JWT on success. checkPeerGroupAccess fails closed when a private service has empty AccessGroups.
- ValidateSession/ValidateTunnelPeer responses now carry peer_group_ids + peer_group_names so the proxy can authorise policy-aware middlewares without an extra management round-trip.
- ProxyInboundListener + SendStatusUpdate.inbound_listener: per-account inbound listener state surfaced to dashboards.
- PathTargetOptions.direct_upstream (11): bypass the embedded NetBird client and dial the target via the proxy host's network stack for upstreams reachable without WireGuard.
Data model
- Service.Private (bool) + Service.AccessGroups ([]string, JSON- serialised). Validate() rejects bearer auth on private services. Copy() deep-copies AccessGroups. pgx getServices loads the columns.
- DomainConfig.Private threaded into the proxy auth middleware. Request handler routes private services through forwardWithTunnelPeer and returns 403 on validation failure.
- Account-level SynthesizePrivateServiceZones (synthetic DNS) and injectPrivateServicePolicies (synthetic ACL) gate on len(svc.AccessGroups) > 0.
Proxy
- /netbird proxy --private (embedded mode) flag; Config.Private in proxy/lifecycle.go.
- Per-account inbound listener (proxy/inbound.go) binding HTTP/HTTPS on the embedded NetBird client's WireGuard tunnel netstack.
- proxy/internal/auth/tunnel_cache: ValidateTunnelPeer response cache with single-flight de-duplication and per-account eviction.
- Local peerstore short-circuit: when the inbound IP isn't in the account roster, deny fast without an RPC.
- proxy/server.go reports SupportsPrivateService=true and redacts the full ProxyMapping JSON from info logs (auth_token + header-auth hashed values now only at debug level).
Identity forwarding
- ValidateSessionJWT returns user_id, email, method, groups, group_names. sessionkey.Claims carries Email + Groups + GroupNames so the proxy can stamp identity onto upstream requests without an extra management round-trip on every cookie-bearing request.
- CapturedData carries userEmail / userGroups / userGroupNames; the proxy stamps X-NetBird-User and X-NetBird-Groups on r.Out from the authenticated identity (strips client-supplied values first to prevent spoofing).
- AccessLog.UserGroups: access-log enrichment captures the user's group memberships at write time so the dashboard can render group context without reverse-resolving stale memberships.
OpenAPI/dashboard surface
- ReverseProxyService gains private + access_groups; ReverseProxyCluster gains private + supports_private. ReverseProxyTarget target_type enum gains "cluster". ServiceTargetOptions gains direct_upstream. ProxyAccessLog gains user_groups.
The cluster listing now answers three questions in one round-trip
instead of forcing the dashboard to cross-reference the domains API:
which clusters can this account see, are they currently up, and what
do they support. The ProxyCluster wire type drops the boolean
self_hosted in favour of a `type` enum (`account` / `shared`) plus
explicit `online`, `supports_custom_ports`, `require_subdomain`, and
`supports_crowdsec` fields.
Store query reworked so offline clusters still appear (no last_seen
WHERE), with online and connected_proxies both derived from the
existing 2-min active window via portable CASE expressions; the
1-hour heartbeat reaper still removes long-stale rows. Service
manager enriches each cluster with the capability flags via the
existing per-cluster lookups (CapabilityProvider now also exposes
ClusterSupportsCrowdSec).
GetActiveClusterAddresses* keep their tight 2-min filter so service
routing and domain enumeration aren't pulled into the wider window.
The hard cut removes self_hosted from the response — the dashboard is
the only consumer and is updated in the matching PR; no transitional
field is shipped.
Adds a cross-engine regression test asserting offline clusters
surface, connected_proxies counts only fresh proxies, and
account-scoped BYOP clusters never leak across accounts.
