Is UPnP for ARC safe?

All they have to do is breach your network and pretend to be an ordinarily benign device, like an air conditioner or a Smart TV, and send your router a port forwarding request.”

AFTER they have already breached your network, they can already do what they want and they don’t need UPnP anymore for anything.

Communication with the Internet protocol works with IP addresses and open ports. Open ports can be secured or the internet as we know it would not exist.

There is a long thread here:

Security with Roon ARC / Roon 2.0

Finally got my set up to work. Since the port is now open on both the ISP router for the wired mesh network and on the access point for the wired roon core, how are we ensuring proper security with that port open? Thoughts appreciated.
