router_port_reserved

HTTP 409 This public port is reserved for router management

What happened

The public port of the forward covers the port the platform uses to manage the router. Forwarding it would hand the router's control plane to the internet and make the router unmanageable.

What to do

Pick another public port or a range that does not include the management port, then repeat with the same idempotency key.

Retrying

Change the state this refers to, then repeat the same request with the same idempotency key.
