Thank you antinode.

I looked where you suggested (UPnP?   (ADVANCED > Advanced Setup > UPnP)) and found that indeed it maps

TCP 554 to 10.0.0.18

TCP 1935 to 10.0.0.18

UDP 6000 to 10.0.0.18

UDP 6002 to 10.0.0.18

Didn't know about this. From my perspective this presents a HUGE security hole.

I use my router and its nat capabilities to secure my network.

This blows a huge hole in it.

"UPnP doesn’t require any sort of authentication from the user. Any application running on your computer can ask the router to forward a port over UPnP, which is why the malware above can abuse UPnP."

Is there a way to disable UPnP on the C7000v2 Nighthawk router?
