Hola colegas: estoy poseditando un video sobre SD-WAN y no sé cómo traducir este término: trombone that traffic back

Encontré la definición pero no estoy segura de haberla interpretado correctamente (https://blog.ipspace.net/2011/02/traffic-trombone-what-it-is...

Este es el segmento:

And it will strip out that MPLS tagging and then trombone that traffic back out to an interface that gives access to the internet.

Mi intento: Eliminará la etiqueta MPLS y luego enviará en bucle ese tráfico a una interfaz que permite el acceso a Internet.

Más contexto: (time tag son las etiquetas)
They're doing some training, and they need to do some research.
And it will strip out that MPLS tagging and then trombone that traffic back out to an interface that gives access to the internet.
That traffic will return back to the corporate structure.
The corporate structure then will repackage that information and then direct it back to the branch office.
If you've got lots of branch offices, this puts a significant amount of burden on that corporate infrastructure for what's easily identified as simple internet traffic that maybe, if you had policy shaping that took place at that branch office, you could identify and discriminate.

Gracias por su sugerencias!
