I'm seeing unsolicited connection attempts on UDP ports 53180 and 53181 from three units on my local network - two LS Pro Duo's and a TeraStation. These are listed as private / custom ports, not registered with IANA.
Before I just open those ports up on the Firewall I'd like to understand a) are the connection attempts valid, and if so b) what the units are attempting to do. I just do not want to open up ports unnecessarily.
I've not found any reference to these on the knowledge base or FAQ's. Any group experiences with them?
TIA
