Rule rejected TCP(6) traffic with (10.0.0.1 Port ?)

I uninstalled NIS 2013 because history log full report wasn't updating. Then I downloaded and reinstalled NIS 2013. I am at version 21.0.1.3   In my history log I now have alot of entries that I have never seen before. they read:

 

Rule rejected TCP(6) traffic with (10.0.0.1 Port (????) ) with the numbers in question marks changing upwards.

 

Does anybody know what these logs mean and are they ok?

 

Thanks Kevin
