To design solutions where a destination IP may match both a Cloudflare Tunnel private network route and a Magic Networking route, consult your solutions engineer for guidance.

When a destination IP matches both a Cloudflare Tunnel private network route and a Magic Networking route, Cloudflare Tunnel takes precedence. This happens whenever a `cloudflared` tunnel CIDR matches a packet, regardless of prefix length. For example, a `cloudflared` tunnel with prefix `10.1.2.0/24` takes precedence over a static route configured to `10.1.2.4/32`, and Cloudflare sends packets over the tunnel instead of a GRE tunnel.

To check if a `cloudflared` tunnel is working properly with your Magic WAN connection, open a browser from a host behind your customer premise equipment, and browse to the `cloudflared` tunnel endpoint.

For example, imagine you have a Cloudflare Tunnel set up with a private network CIDR of `10.1.2.3/32`, a static route defined in Magic WAN for `10.1.2.3/24`, and the device you are trying to connect to is a web server. You can test connectivity to the web server by using a browser to load `https://10.1.2.3`. If the page loads correctly, your Cloudflare Tunnel is working properly. In this scenario, you have overlapping routes defined for Cloudflare Tunnel and Magic WAN.

As mentioned above, if you have overlapping routes in your Magic WAN and Cloudflare Tunnel routing configurations, Cloudflare Tunnel will take precedence. This happens whenever a `cloudflared` tunnel CIDR matches a packet, regardless of prefix length. For example, a `cloudflared` tunnel with prefix `10.1.2.0/24` will take precedence over a static route configured to `10.1.2.4/32`, sending packets over a GRE tunnel.

1. From a host behind your customer premises equipment, open a browser.

2. Browse to an IP address or hostname that is reachable through a Cloudflare Tunnel private network route, such as the example destination `10.1.2.3`.
31+
3. Confirm that the application loads as expected.

If the application loads correctly, Cloudflare Tunnel is handling the traffic as configured.
