Insight graphs

[VEbzuT6X]

Hey,

I've got as couple of questions re. Insights graphs.
First, does anyone know what mystery interface '9' is in the image below?
I don't see it often but when I do I can see no reason for it.



Also, does anyone know if Insight displays both sender and responder port numbers?



I don't have port 30243 open in my firewall, so what am I seeing here?

Thanks!
