Changelog

You can now define custom applications for breakout and prioritized traffic on the Cloudflare One Appliance directly from the dashboard, without calling the API.

• In Traffic Steering > Breakout traffic or Prioritized traffic, select Assign application traffic > Add to create a custom application matched by Hostnames, IP subnets, and/or the new Source subnets field, alongside Cloudflare-managed applications.
• Edit or delete an existing custom application from the same panel, no API round-trip required.
• Source subnets lets you match traffic by its source IP range, complementing the existing source LAN interface breakout criteria.

This complements the existing API and Terraform workflow for managing applications.

For details, refer to Breakout traffic and Prioritized traffic.

You can now configure custom DHCP options directly from the dashboard when the Cloudflare One Appliance is acting as the DHCP server for a LAN.

• In LAN configuration, under DHCP server options, select Add DHCP option to choose from common options for PXE / iPXE boot, VoIP phone provisioning, and vendor-specific configuration, or select Add custom option to enter your own option code, type, and value.
• This complements the existing API and Terraform workflow for configuring DHCP options.

For details, refer to DHCP server options.

When you register a Cloudflare One Virtual Appliance, you can now select your hypervisor and download the appliance directly from the dashboard — no need to look up asset URLs.

• On the Connectors page, select Add an appliance, choose Virtual appliance, then select your hypervisor: VMware ESXi, Proxmox, or libvirt/KVM.
• Download the OVA image (VMware ESXi) or the install script (Proxmox and libvirt/KVM) for the selected hypervisor.
• Use View setup guide to open deployment instructions for your platform.

This complements the existing self-serve registration and license key generation in the dashboard.

For details, refer to Configure a Cloudflare One Virtual Appliance.

You can now restart, reboot, or shut down a Cloudflare One Appliance directly from the dashboard or via API.

• Restart — Restart managed services. Purges temporary and (optionally) persistent state.
• Reboot — Power cycle the appliance. Optionally, purge persistent state. Re-applies configuration starting from scratch.
• Shutdown — Power off the appliance. Optionally, purge persistent state. The machine will be offline until manually powered on again.

In the dashboard, go to Networking > Connectors > Appliances, select an appliance, then Edit > Operations to send an operation. Via API, POST to the /accounts/{account_id}/magic/connectors/{connector_id}/interrupts endpoint.

For details, refer to Appliance operations.

You can now register a Cloudflare One Virtual Appliance and generate its license key directly from the dashboard, without contacting your account team.

• On the Connectors page, select Add an appliance and choose Virtual appliance to register a virtual appliance and generate its authentication key.
• Use Regenerate authentication key from a virtual appliance connector's menu to rotate its key. The previous key is immediately and irrevocably revoked.
• The authentication key is shown only once — copy and store it securely.

This complements the existing API and Terraform self-serve workflow for provisioning virtual appliances. Hardware appliances continue to use the existing account-team fulfillment workflow.

For details, refer to Configure a Cloudflare One Virtual Appliance.

When the Cloudflare One Appliance is acting as the DHCP server for a LAN, you can now configure custom DHCP options on the leases it issues. This unlocks workflows such as PXE / iPXE boot, VoIP phone provisioning, and vendor-specific client configuration.

Each option is defined by option_number, value, and one of four value types: text, integer, hex, or ip. Configurations are validated on the appliance before being applied — invalid configurations are rejected and the underlying error is returned to the API caller, so a bad option will not disrupt the live DHCP service.

For details, refer to DHCP server options.

Breakout and traffic prioritization rules on the Cloudflare One Appliance can now match by source in addition to destination application. You can pin breakout or priority behavior to:

• A source LAN interface — VLANs attached to that LAN are included automatically.
• A source IP address, range, or CIDR block.

This is the natural way to break out a guest VLAN to the local Internet, or to prioritize traffic from a specific subnet, without enumerating destination applications.

For details, refer to Breakout traffic.

You can now create, rotate, and delete Cloudflare One Virtual Appliance instances and their license keys directly via the API and Terraform.

• Create a virtual appliance and receive a license key: POST /accounts/{account_id}/magic/connectors with device.provision_license: true.
• Rotate the license key for an existing virtual appliance: PATCH /accounts/{account_id}/magic/connectors/{connector_id} with provision_license: true. The previous key is immediately and irrevocably revoked.
• Delete a virtual appliance to release the associated licensed device.

The license key is returned in the response only once, at create or rotate time. Copy and store it securely.

For details, refer to Configure a Cloudflare One Virtual Appliance.

Cloudflare One Appliance now supports Link Aggregation Control Protocol (LACP), allowing you to bundle up to six physical LAN ports into a single logical interface. Link aggregation increases available bandwidth and eliminates single points of failure on the LAN side of the appliance.

This feature is available in beta on physical appliance hardware with the latest OS. No entitlement is required.

To configure a Link Aggregation Group, refer to Configure link aggregation groups.

Cloudflare One Appliance version 2026.2.0 adds post-quantum encryption support using hybrid ML-KEM (Module-Lattice-Based Key-Encapsulation Mechanism).

The appliance now uses TLS 1.3 with hybrid ML-KEM for its connection to the Cloudflare edge. During the TLS handshake, the appliance and the edge share a symmetric secret over the TLS connection and inject it into the ESP layer of IPsec. This protects IPsec data plane traffic against harvest-now, decrypt-later attacks.

This upgrade deploys automatically to all appliances during their configured interrupt windows with no manual action required.

For more information, refer to Cloudflare One Appliance.

Magic WAN Connector now exports NetFlow data for breakout traffic to Magic Network Monitoring (MNM), providing visibility into traffic that bypasses Cloudflare's security filtering.

This feature allows you to:

• Monitor breakout traffic statistics in the Cloudflare dashboard.
• View traffic patterns for applications configured to bypass Cloudflare.
• Maintain visibility across all traffic passing through your Magic WAN Connector.

For more information, refer to NetFlow statistics.

Magic WAN Connector now allows you to designate a specific WAN port for breakout traffic, giving you deterministic control over the egress path for latency-sensitive applications.

With this feature, you can:

• Pin breakout traffic for specific applications to a preferred WAN port.
• Ensure critical traffic (such as Zoom or Teams) always uses your fastest or most reliable connection.
• Benefit from automatic failover to standard WAN port priority if the preferred port goes down.

This is useful for organizations with multiple ISP uplinks who need predictable egress behavior for performance-sensitive traffic.

For configuration details, refer to Designate WAN ports for breakout apps.

The KVM-based virtual Cloudflare One Appliance is now in open beta with official support for Proxmox VE.

Customers can deploy the virtual appliance on KVM hypervisors to connect branch or data center networks to Cloudflare WAN without dedicated hardware.

For setup instructions, refer to Configure a virtual Cloudflare One Appliance.

Cloudflare One Appliance DHCP server settings now support specifying multiple DNS server IP addresses in the DHCP pool.

Previously, customers could only configure a single DNS server per DHCP pool. With this update, you can specify multiple DNS servers to provide redundancy for clients at branch locations.

For configuration details, refer to DHCP server.

You can now locally configure your Magic WAN Connector to work in a static IP configuration.

This local method does not require having access to a DHCP Internet connection. However, it does require being comfortable with using tools to access the serial port on Magic WAN Connector as well as using a serial terminal client to access the Connector's environment.

For more details, refer to WAN with a static IP address.
