Inbound Scan

Typically inbound traffic to this port is Messenger Spam which is more annoying then anything else, and hence not really worthy of a Link Logger alert, but still there is enough of this traffic that an explanation is helpful.

Outbound Scan

Outbound scans, if occurring in volume should be considered an indication of a possible worm infection on the source computer and should be investigated.
