## Using an External Gateway with Rancher
When using the Gateway API network exposure type, Rancher can create and manage its own Gateway resource. However, if you have an existing Gateway that you manage independently (for example, a shared Gateway used by multiple applications), you will need to create your own HTTPRoute resources to route traffic to Rancher.
This section covers how to create the required HTTPRoute resources manually when using an externally managed Gateway.

## Cross-Namespace Gateway Requirements
If your Gateway is in a different namespace than Rancher (e.g., Gateway in `gateway-system`, Rancher in `cattle-system`), the Gateway must be configured to accept HTTPRoutes from the Rancher namespace. By default, Gateway API only allows routes from the same namespace as the Gateway.
