I'm at a bit of a loss as to what could be port scanning. My ISP was not helpful in giving me enough information to diagnose the issue, UDP traffic on a random port could be legitimate traffic.

- the date of the instance (there has been more than one)
- the port that was scanned (they had provided more than one, 2933 and 40473 were among them)
- the source IP of the scan, which is my public IP
- that it was done via UDP
