   Additional notes

   • Change Event::NewExternalAddr and Event::ExpiredExternalAddr from tuple variants to struct variants that include both local and external addresses. This allows users to correlate which local listen address was mapped to which external address.

     • Event::NewExternalAddr now contains local_addr and external_addr fields
     • Event::ExpiredExternalAddr now contains local_addr and external_addr fields See PR 6121.

   • Skip port mapping when an active port mapping is present. Previously, the behavior would skip creating new mappings if any mapping (active or inactive or pending) existed for the same port. Now it correctly only checks active mappings on the gateway. See PR 6127.

   • Fix excessive retry attempts for failed port mappings by implementing exponential backoff. Failed mappings now retry up to 5 times with increasing delays (30s to 480s) before giving up. This prevents continuous retry loops. See PR 6128.
