Changelog

You can now tell a person on a laptop apart from a Mesh node or an AI agent running on Workers, without matching on connector email addresses or Mesh IP ranges — and see exactly which Cloudflare Tunnel and cloudflared replica received each session.

Gateway network logs and Zero Trust Network Session Logs now identify two new kinds of traffic:

• Mesh — Traffic sent from or delivered to a Cloudflare Mesh node. Previously, Mesh nodes were logged the same way as devices running the Cloudflare One Client, because Mesh nodes run the client in headless mode.
• Workers VPC — Traffic sent by a Worker through a Workers VPC binding. Previously, Workers VPC sessions were not recorded in Network Session Logs.

To view these values in the dashboard, go to Zero Trust > Insights & Logs > Logs > Network logs, select Columns, and turn on Traffic Source and Traffic Destination. Both values also appear under Network query details when you open a log entry.

The zero_trust_network_sessions dataset, available through Logpush, includes the following fields:

For example, OnrampType = 'WORKERS_VPC' AND Offramp = 'MESH' returns every session where a Worker reached a service behind a Mesh node, and SourceName tells you which Worker it was.

With DestinationReplicaID, you can now confirm which Cloudflare Tunnel and which cloudflared replica received traffic for a specific session. Combine it with the existing DestinationTunnelID field to trace a session to an exact tunnel replica — or Mesh node replica — when you run multiple replicas for high availability. The replica ID matches the Connector ID shown in the dashboard, so you can stream that replica's logs with cloudflared tail --connector-id.

Sessions logged before this change are not backfilled. For all available fields, refer to Zero Trust Network Session Logs.

VPC Network bindings now support the connect() Socket API for raw TCP connections to private destinations, in addition to HTTP traffic via fetch().

This means Workers can now open TCP sockets to any private service reachable through the bound Cloudflare Tunnel, Cloudflare Mesh, or Cloudflare WAN on-ramp — Redis, Memcached, MQTT, custom binary protocols, or any other TCP-based service.

{
  "$schema": "./node_modules/wrangler/config-schema.json",
  "vpc_networks": [
    {
      "binding": "PRIVATE_NETWORK",
      "network_id": "cf1:network",
      "remote": true
    }
  ]
}

[[vpc_networks]]
binding = "PRIVATE_NETWORK"
network_id = "cf1:network"
remote = true

At runtime, use connect() on the binding to open a TCP socket to a private destination:

export default {
	async fetch(request: Request, env: Env) {
		// Open a TCP connection to a private Redis instance
		const socket = await env.PRIVATE_NETWORK.connect("10.0.1.50:6379");

		// Write a Redis PING command
		const writer = socket.writable.getWriter();
		await writer.write(new TextEncoder().encode("PING\r\n"));
		await writer.close();

		return new Response(socket.readable);
	},
};

For more details, refer to VPC Networks and the Workers Binding API.

Workers using a VPC Network binding with network_id: "cf1:network" now egress to public Internet destinations through Cloudflare Gateway. This means your existing Zero Trust traffic policies — DNS, HTTP, Network, and egress — extend to traffic that originates from your Workers, the same way they do for WARP users today.

What you get by default:

• Visibility. Worker egress shows up in Gateway DNS, HTTP, and Network logs alongside your other traffic, so you can audit what your Workers are calling and when.
• Enforcement. Any existing Gateway policy whose selectors match a Worker request will apply — including allow / block lists, DNS category filtering, and HTTP destination rules. If you have already blocked a category for your workforce, your Workers inherit that block.

{
	"vpc_networks": [
		{
			"binding": "EGRESS",
			"network_id": "cf1:network",
			"remote": true,
		},
	],
}

[[vpc_networks]]
binding = "EGRESS"
network_id = "cf1:network"
remote = true

// Egress to a public destination — subject to your Gateway policies and logged
const response = await env.EGRESS.fetch("https://api.example.com/data");

// Egress to a public destination — subject to your Gateway policies and logged
const response = await env.EGRESS.fetch("https://api.example.com/data");

For configuration options, refer to VPC Networks. For policy authoring, refer to Cloudflare Gateway traffic policies.

You can now use VPC Network bindings with network_id: "cf1:network" to reach your full private network from Workers, including:

• Cloudflare Mesh nodes and client devices
• Subnet routes and hostname routes announced through Cloudflare Tunnel or Cloudflare Mesh
• Destinations connected through Cloudflare WAN on-ramps — GRE, IPsec, and CNI

This means a single VPC Network binding can route Worker requests to private services regardless of how those services are connected to Cloudflare: through a Cloudflare Tunnel from a cloud VPC, a Mesh node on a private subnet, or a Cloudflare WAN on-ramp from your data center or branch site.

{
	"vpc_networks": [
		{
			"binding": "PRIVATE_NETWORK",
			"network_id": "cf1:network",
			"remote": true,
		},
	],
}

[[vpc_networks]]
binding = "PRIVATE_NETWORK"
network_id = "cf1:network"
remote = true

At runtime, the URL you pass to fetch() determines the destination:

// Reach a service behind a Cloudflare WAN IPsec on-ramp
const response = await env.PRIVATE_NETWORK.fetch("http://10.50.0.100:8080/api");

For configuration options, refer to VPC Networks.

VPC Network bindings now give your Workers access to any service in your private network without pre-registering individual hosts or ports. This complements existing VPC Service bindings, which scope each binding to a specific host and port.

You can bind to a Cloudflare Tunnel by tunnel_id to reach any service on the network where that tunnel is running, or bind to your Cloudflare Mesh network using cf1:network to reach any Mesh node, client device, or subnet route in your account:

{
  "vpc_networks": [
    {
      "binding": "MESH",
      "network_id": "cf1:network",
      "remote": true
    }
  ]
}

[[vpc_networks]]
binding = "MESH"
network_id = "cf1:network"
remote = true

At runtime, fetch() routes through the network to reach the service at the IP and port you specify:

const response = await env.MESH.fetch("http://10.0.1.50:8080/api/data");

For configuration options and examples, refer to VPC Networks and Connect Workers to Cloudflare Mesh.

Each VPC Service now has a Metrics tab so you can monitor connection health and debug failures without leaving the dashboard.

• Connections — See successful and failed connections over time, broken down by what is responsible: your origin (Bad Upstream), your configuration (Client), or Cloudflare (Internal).
• Latency — Track connection and DNS resolution latency trends.
• Errors — Drill into specific error codes grouped by category, with filters to isolate upstream, client, or internal failures.

You can also view and edit your VPC Service configuration, host details, and port assignments from the Settings tab.

For a full list of error codes and what they mean, refer to Troubleshooting.

Workers VPC now supports Cloudflare Origin CA certificates when connecting to your private services over HTTPS. Previously, Workers VPC only trusted certificates issued by publicly trusted certificate authorities (for example, Let's Encrypt, DigiCert).

With this change, you can use free Cloudflare Origin CA certificates on your origin servers within private networks and connect to them from Workers VPC using the https scheme. This is useful for encrypting traffic between the tunnel and your service without needing to provision certificates from a public CA.

For more information, refer to Supported TLS certificates.

Workers VPC Services is now available, enabling your Workers to securely access resources in your private networks, without having to expose them on the public Internet.

• VPC Services: Create secure connections to internal APIs, databases, and services using familiar Worker binding syntax
• Multi-cloud Support: Connect to resources in private networks in any external cloud (AWS, Azure, GCP, etc.) or on-premise using Cloudflare Tunnels

export default {
	async fetch(request, env, ctx) {
		// Perform application logic in Workers here

		// Sample call to an internal API running on ECS in AWS using the binding
		const response = await env.AWS_VPC_ECS_API.fetch("https://internal-host.example.com");

		// Additional application logic in Workers
		return new Response();
	},
};

Set up a Cloudflare Tunnel, create a VPC Service, add service bindings to your Worker, and access private resources securely. Refer to the documentation to get started.
