I'm seeing the something similar.  Last Sunday and Monday, there
was about 2000/day.  Since then, it has only been about 180/day.
Same as you...random port.

Looks to me like some kind of back-scatter from a DDoS... (But I would
think the SYN would be set)  Looks like last Sun/Mon was the brunt of
the attack.  What has been going on since Mon is probably just
some residual noise that isn't effecting  them that much.
