Reinstates the SyncMappings RPC that landed on origin/main and the
client-side fallback to GetMappingUpdate.
- proto: SyncMappings RPC + SyncMappingsRequest{Init|Ack} +
SyncMappingsResponse messages.
- management proxy.go: SyncMappings server handler, recvSyncInit,
sendSnapshotSync (per-batch send-then-wait-for-ack), drainRecv,
waitForAck; proxyConnection.syncStream + sendResponse routes the
same sendChan onto the bidi stream when set.
- proxy/server.go: trySyncMappings + handleSyncMappingsStream that
acks after each batch is processed; outer loop tries SyncMappings
first and falls back to GetMappingUpdate on Unimplemented.
Capabilities lifted into proxyCapabilities() so both code paths
use the same flags.
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.
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
* **New Features**
* Access logs now include bytes_upload and bytes_download (API and schemas updated, fields required).
* Certificate issuance duration is now recorded as a metric.
* **Refactor**
* Metrics switched from Prometheus client to OpenTelemetry-backed meters; health endpoint now exposes OpenMetrics via OTLP exporter.
* **Tests**
* Metric tests updated to use OpenTelemetry Prometheus exporter and MeterProvider.
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.
* **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.
Two new boolean flags, SearchDomainDisabled and SkipPTRProcess, are added to CustomZone and its protobuf; they are propagated through the engine to DNS host logic. Host matching now uses SearchDomainDisabled directly, and PTR collection skips zones with SkipPTRProcess; reverse zones are initialized with SearchDomainDisabled: true.
- Port dnat changes from https://github.com/netbirdio/netbird/pull/4015 (nftables/iptables/userspace)
- For userspace: rewrite the original port to the target port
- Remember original destination port in conntrack
- Rewrite the source port back to the original port for replies
- Redirect incoming port 5353 to 22054 (tcp/udp)
- Revert port changes based on the network map received from management
- Adjust tracer to show NAT stages
makes the DNS forwarder port configurable in the management and client components, while changing the well-known port from 5454 to 22054. The change includes version-aware port assignment to ensure backward compatibility.
- Adds a configurable `ForwarderPort` field to the DNS configuration protocol
- Implements version-based port computation that returns the new port (22054) only when all peers support version 0.59.0 or newer
- Updates the client to dynamically restart the DNS forwarder when the port changes
