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.
When closing go routines and handling peer disconnect, we should avoid canceling the flow due to parent gRPC context cancellation.
This change triggers disconnection handling with a context that is not bound to the parent gRPC cancellation.
* Add support for legacy IDP cache environment variable
* Centralize cache store creation to reuse a single Redis connection pool
Each cache consumer (IDP cache, token store, PKCE store, secrets manager,
EDR validator) was independently calling NewStore, creating separate Redis
clients with their own connection pools — up to 1400 potential connections
from a single management server process.
Introduce a shared CacheStore() singleton on BaseServer that creates one
store at boot and injects it into all consumers. Consumer constructors now
receive a store.StoreInterface instead of creating their own.
For Redis mode, all consumers share one connection pool (1000 max conns).
For in-memory mode, all consumers share one GoCache instance.
* Update management-integrations module to latest version
* sync go.sum
* Export `GetAddrFromEnv` to allow reuse across packages
* Update management-integrations module version in go.mod and go.sum
* Update management-integrations module version in go.mod and go.sum
Remove client secret from gRPC auth flow. The secret was originally included to support providers like Google Workspace that don't offer a proper PKCE flow, but this is no longer necessary with the embedded IdP. Deployments using such providers should migrate to the embedded IdP instead.
Auto-update logic moved out of the UI into a dedicated updatemanager.Manager service that runs in the connection layer. The
UI no longer polls or checks for updates independently.
The update manager supports three modes driven by the management server's auto-update policy:
No policy set by mgm: checks GitHub for the latest version and notifies the user (previous behavior, now centralized)
mgm enforces update: the "About" menu triggers installation directly instead of just downloading the file — user still initiates the action
mgm forces update: installation proceeds automatically without user interaction
updateManager lifecycle is now owned by daemon, giving the daemon server direct control via a new TriggerUpdate RPC
Introduces EngineServices struct to group external service dependencies passed to NewEngine, reducing its argument count from 11 to 4
Consolidate all expose business logic (validation, permission checks, TTL tracking, reaping) into the manager layer, making the gRPC layer a pure transport adapter that only handles proto conversion and authentication.
- Add ExposeServiceRequest/ExposeServiceResponse domain types with validation in the reverseproxy package
- Move expose tracker (TTL tracking, reaping, per-peer limits) from gRPC server into manager/expose_tracker.go
- Internalize tracking in CreateServiceFromPeer, RenewServiceFromPeer, and new StopServiceFromPeer so callers don't manage tracker state
- Untrack ephemeral services in DeleteService/DeleteAllServices to keep tracker in sync when services are deleted via API
- Simplify gRPC expose handlers to parse, auth, convert, delegate
- Remove tracker methods from Manager interface (internal detail)
CLI: new expose command to publish a local port with flags for PIN, password, user groups, custom domain, name prefix and protocol (HTTP default).
Management/API: create/renew/stop expose sessions (streamed status), automatic naming/domain, TTL renewals, background expiration, new management RPCs and client methods.
UI/API: account settings now include peer_expose_enabled and peer_expose_groups; new activity codes for peer expose events.
* Add gRPC update debouncing mechanism
Implements backpressure handling for peer network map updates to
efficiently handle rapid changes. First update is sent immediately,
subsequent rapid updates are coalesced, ensuring only the latest
update is sent after a 1-second quiet period.
* Enhance unit test to verify peer count synchronization with debouncing and timeout handling
* Debounce based on type
* Refactor test to validate timer restart after pending update dispatch
* Simplify timer reset for Go 1.23+ automatic channel draining
Remove manual channel drain in resetTimer() since Go 1.23+ automatically
drains the timer channel when Stop() returns false, making the
select-case pattern unnecessary.
When a deleted peer tries to reconnect, GetUserIDByPeerKey was returning
Internal error instead of NotFound, causing clients to retry indefinitely
instead of recognizing the unrecoverable PermissionDenied error.
This fix:
1. Updates GetUserIDByPeerKey to properly return NotFound when peer doesn't exist
2. Updates Sync handler to convert NotFound to PermissionDenied with message
'peer is not registered', matching the behavior of GetAccountIDForPeerKey
Fixes the regression introduced in v0.61.1 where deleted peers would see:
- Before: 'rpc error: code = Internal desc = failed handling request' (retry loop)
- After: 'rpc error: code = PermissionDenied desc = peer is not registered' (exits)
* **New Features**
* SSH server JWT validation now accepts multiple audiences with backward-compatible handling of the previous single-audience setting and a guard ensuring at least one audience is configured.
* **Tests**
* Test suites updated and new tests added to cover multiple-audience scenarios and compatibility with existing behavior.
* **Other**
* Startup logging enhanced to report configured audiences for JWT auth.
Embed Dex as a built-in IdP to simplify self-hosting setup.
Adds an embedded OIDC Identity Provider (Dex) with local user management and optional external IdP connectors (Google/GitHub/OIDC/SAML), plus device-auth flow for CLI login. Introduces instance onboarding/setup endpoints (including owner creation), field-level encryption for sensitive user data, a streamlined self-hosting provisioning script, and expanded APIs + test coverage for IdP management.
