I do have traffic shaping on the *external* interface, but it is not port
dependent.

tc class|filter show dev <internal_interface> gives an empty response.

Also, when I clear the queue (I use wondershaper, so running wondershaper
clear), it seems I still have the same problem.

...But is there some way that outbound traffic shaping on the external
facing interface could somehow impact *inbound* HTTP traffic on an internal
client connected to the internal facing interface?
