WARP on-ramp to Magic WAN
Use WARP as an on-ramp to Magic WAN and route traffic from user devices with WARP installed to any network connected with Cloudflare Tunnel or Magic IP-layer tunnels (Anycast GRE, IPsec, or CNI).
Prerequisites
Before you can begin using WARP as an on-ramp to Magic WAN, you must:
- Set up your Zero Trust account.
- Contact your account team to enable the integration between WARP and Magic WAN.
1. Create a service token
Refer to Create a service token in the Cloudflare Zero Trust documentation for more information.
2. Install the WARP client on your device
Refer to Install the WARP client on your devices in the Cloudflare Zero Trust documentation for more information.
3. Configure Split Tunnels
Configure Split Tunnels from your Zero Trust account to only include traffic from the private IP addresses you want to acceess.
Optionally, you can configure Split Tunnels to include IP ranges or domains you want to use for connecting to public IP addresses. If you choose to use this option, destination ports 1023 and lower are supported.
4. Connect to WARP from your machine
Refer to Deploy WARP to your organization for more information on whether to choose a manual or managed deployment.
You should be able to access Private IP addresses specified in the Split Tunnel configuration. If you requested to test TCP connectivity to public IP addresses, you should be able to access these services provided the destination port is 1023 or lower.
5. Route packets back to WARP devices
Route packets back to WARP devices from services behind an Anycast GRE or other type tunnel.
WARP devices will be assigned IP addresses from the Magic WARP Virtual IP (VIP) space. To view your virtual IP address, open the Cloudflare Zero Trust dashboard and select My Team > Devices.
All packets with a destination IP in the VIP space need to be routed back through the tunnel. For example, with a single GRE tunnel named gre1, in Linux, the following command would add a routing rule that would route such packets:
ip route add 100.96.0.0/12 dev gre1
