I don't get it. Why report anything to the product team if it is "as intended?"
Regardless -- I'm glad that you did forward the report. This has to be a bug -- it may simply be that something is being incorrectly displayed (which is how I'm leaning, as packets captured in the log are generally the packets that are NOT going through).
The original DSLReport's post (which is very confusing) suggests that something is egressing out the WAN side. But other than that first reporter, nobody else is seeing anything of major concern.
Anyway, thanks for forwarding it along.
