Gateway, Cloudflare Mesh, Workers VPC - Filter Workers' public Internet traffic using Gateway policies

June 5, 2026Developer Platform ChangelogView original ↗

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.

  1. Worker

    Calls env.EGRESS.fetch()

  2. VPC binding ↓

  3. Cloudflare Mesh

    Bind via cf1:network

  4. ↓

  5. Cloudflare Gateway

    Policies applied:

    DNS HTTP Network

  6. ↓

  7. ↗ Public Internet

    Any public hostname or IP

Gateway logs DNS HTTP Network

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.
