Here’s my understanding of port forwarding. We had an intruder who had access to my computers and they may well have set up some malicious port forwarding. So, either 1) I have scanned my neighbour’s smart fridge by mistake, or 2) this is the Blink XT sync module and there appears to be an open port 53 on it.īlink tech support say there shouldn’t be any open ports associated with the device so if anyone with an XT sync module can confirm that they have no open ports on it then at least I know I have a localised network problem to deal with.

OS details: OpenWrt Barrier Breaker (Linux 3.10) MAC Address: 00:03:xx:xx:xx:xx (Atheros Communications) An extract of the results is shown below (some IDs are redacted)ĭiscovered open port 53/tcp on 192.168.0.xx OKaaay… so I ran nmap (using Zenmap GUI) on two Linux PCs on the network and targetted the Blink module IP address.
