For some reason my work laptop is giving the following alarm, UDP Port 55128 on device, 'My Laptop' is open to the public permanently for Teredo xxx.xxx.xxx.xxx:55128->55128 UDP.
Does anyone know why I am getting this alert? My laptop and other devices are connected to NordVPN configured on the Firewalla Gold. My work IT department has no idea.
Should I block this open port? I believe I blocked a similar alert sometime ago, but was/am still able to access work resources remotely. I get this message, different ports, sporadically.
