Linksys Router

I have a Linksys router also and recently had to switch to cable modem from
DSL due to a recent move.  I also run the Zone Alarm.  Since the switch I
have been noticing the Zone Alarm messages about denying some kind of TCP
request (not sure the exact message right now) that I did not experience
with the DSL line.  

The question that I have is:  
Could this be someone hacking into my router and then trying to get to my
PC's that are connected to it?

 The FIRST
thing I did was get a Linksys router to do NAT. Also use Zone Alarm and
Sophos Antivirus (from your neck of the woods, by the way). If you connect
up to the internet without this stuff your "had". I saw something a couple
of weeks ago that said once you connect, they are I can't remember how many
hundred scans (automated) that find you in a matter of minutes and then
attacks coming back against that with the hour ! Unreal.
