Port Blocking question

NAV2008

 

Ok I had someting like this awhile back and now I notice it again

 

Normally the activity log for my NAV2008 will show frequent entries of

Port Blocking allowed 192.168.0.1(8).

which I believe to be my DSL box

 

 

But tonight there was one entry mixed in that showed

8:36:45pm Port Blocking allowed  64.123.188.255(3).

 

Noe that IP is associated with my ISP but it is not my address. When I check my connection log there shows no connection to my computer at that time 

 

 

so bottom line is this a hack attempt? A worm attempt? Any other malice?

 

scans come up clean and there was only 1 such entry of Port Blocking allowed 64.123.188.255(3). with many entries of Port Blocking allowed 192.168.0.1(8). before and after.

 

so again my biggest concern is this something that is concerning?

Is it someone who has the same ISP as I do trying to do me harm? OR my ISP doing a check? Or something more wicked by a starnger?
