NetBird has released the Reverse Proxy – a feature that fundamentally changes self-hosted setups: Internal services can now be exposed directly to the internet through the WireGuard mesh network, without port forwarding, without firewall rules, with automatic TLS and optional authentication.

What is the NetBird Reverse Proxy?

The NetBird Reverse Proxy exposes internal services running on peers or behind network resources to the public internet. NetBird handles:

• TLS termination with automatic Let's Encrypt certificates or custom certificates
• Optional authentication via SSO (OIDC), password, or PIN
• Traffic routing through encrypted WireGuard tunnels to the target service

The target service needs no public IP address and no open ports. It only needs to be reachable within the NetBird network.

Status: The feature is still labelled beta and is now available both for self-hosted deployments and on NetBird Cloud (as of October 2026, documentation).

How does it work?

The flow for an incoming request:

1. Create a service → NetBird provisions a public domain with a TLS certificate
2. HTTPS request to the domain → TLS termination at the NetBird proxy cluster
3. WireGuard tunnel → The request is forwarded through the encrypted tunnel to the target peer
4. Response follows the same path back

Core Concepts

Each service can have multiple targets for path-based routing. Targets support HTTP and HTTPS as backend protocols.

Authentication: SSO, Password and PIN

Each service can be protected with one or more authentication methods:

Multiple methods can be enabled simultaneously – users choose their preferred method when accessing the service.

For organisations with existing IdP integration (Keycloak, Azure AD, Okta, Google Workspace), SSO is the natural choice: employees authenticate with their existing credentials, and group-based restrictions provide granular access control.

Self-Hosted Setup

Self-hosted deployments require a separate proxy instance (netbirdio/netbird-proxy) that connects to the management server via gRPC.

Prerequisites

• Traefik as reverse proxy (TLS passthrough required – other proxies like Nginx or Caddy do not support this in the required form)
• At least one connected peer or a configured network with resources
• NetBird account with 'Services' permission ('Network Admin' role or higher)

Quick Start

If you deployed NetBird from v0.65.0 onwards using the official setup script (getting-started.sh) with the Traefik option, the proxy container is already included in your Docker Compose stack. Skip straight to creating a service.

For existing deployments, there is a migration guide covering the process: generate an access token, add the proxy container with Traefik labels, set up wildcard DNS.

TLS Certificates

The proxy supports two modes:

ACME (Let's Encrypt):

NB_PROXY_ACME_CERTIFICATES=true
NB_PROXY_ACME_CHALLENGE_TYPE=tls-alpn-01  # or http-01

Static certificates (wildcard or corporate CA):

NB_PROXY_CERTIFICATE_FILE=tls.crt
NB_PROXY_CERTIFICATE_KEY_FILE=tls.key
NB_PROXY_CERTIFICATE_DIRECTORY=./certs

Static certificates support hot-reload – when files change on disk, the proxy picks them up automatically without restart.

High Availability

Multiple proxy instances configured with the same NB_PROXY_DOMAIN value form a cluster. If one instance goes down, the remaining instances continue serving traffic. Each instance independently connects to the management server.

Creating a Service: Step-by-Step

Step 1: Create a Service

In the NetBird dashboard, navigate to Reverse Proxy → Services → Add Service.

Step 2: Configure Details

• Choose a subdomain (e.g., grafana)
• Select a base domain (cluster domain or custom domain)
• Add a target: type (Peer, Host, Domain, Subnet), protocol (HTTP/HTTPS), port
• Optional: path for path-based routing

Step 3: Authentication

In the "Authentication" tab:

• Enable SSO and optionally restrict to groups
• Set a password and/or PIN
• Or leave all disabled for public access

Step 4: Advanced Settings

In the "Settings" tab:

• Pass Host Header – forward the original Host header to the backend (useful when the application needs to know the public domain)
• Rewrite Redirects – rewrite Location headers in backend responses to replace internal URLs

Step 5: Create the Service

After creation, the service progresses through these statuses:

Path-Based Routing and Multi-Target

A service can have multiple targets with different path prefixes:

This consolidates multiple internal services under a single domain – fewer domains, fewer certificates, centralised authentication.

Additionally, the Networks integration provides an "Expose Service" button directly on resources in the Networks view. One click opens the service dialogue with the resource pre-populated as a target.

NetBird Reverse Proxy vs. Alternatives

The key advantage of NetBird: Reverse proxy and mesh VPN come from a single platform. If you already use NetBird for secure network access, you get the reverse proxy without additional infrastructure. With Cloudflare Tunnel or ngrok, traffic flows through external servers – with NetBird, everything stays on your own infrastructure.

Use Cases

Publish Internal Dashboards

Make Grafana, ThingsBoard, or monitoring dashboards accessible to customers or partners – with SSO protection and without requiring a VPN client on the other side.

Share Staging Environments

Share developer previews or QA environments via PIN or password, without setting up VPN access.

Expose IoT Platforms

Securely publish IoT dashboards and APIs running on internal servers – relevant for IoT platforms that provide customer access to sensor data.

Receive Webhooks

Internal services can receive webhooks from GitHub, Stripe, or other providers without needing a public IP.

Temporary Demo Access

PIN or password protection enables time-limited access to internal applications – ideal for demos or proof-of-concepts.

Limitations (Beta)

The feature is in beta with the following limitations:

• Self-hosted needs its own proxy instance: The Reverse Proxy is now available on NetBird Cloud; self-hosted it requires a separate proxy instance (netbirdio/netbird-proxy)
• Traefik required: Other reverse proxies (Nginx, Caddy, HAProxy) are not supported, as TLS passthrough is required
• No Rosenpass: Networks relying on Rosenpass cannot currently use the reverse proxy
• Layer 4 services (TCP, UDP, TLS): Browser-based authentication such as SSO, password or PIN is not available here, only access restrictions by IP address (CIDR), country or CrowdSec IP reputation (NetBird docs)
