Unknown UDP traffic from HA?

I’ve recently added some logging to the internal firewalled devices on my LAN, and I’ve noticed some traffic coming from HA on UDP, all destination ports > 32000.

I’m trying to figure out what this might be, but sofar no idea. Anyone a clue?

EDIT: Put on a wirecapture, and the reason became very clear very quickly: the Hue Bridge Emulation. Hadn’t thought of that.
