I have a linksys router/firewall, and I just recently downloaded ZoneAlarm as a more visual tool for my security experience. I configured the basics for it, and allowed 5 programs access, and then let it run while I went to work for a few hours. Upon coming back, it says that it has blocked 307,545 intrusion attempts, and that 24 of them have been high-rated attacks. So, I'm not sure what's up. I regularly scan my computer with Adaware, and Agnitum's Tauscan, and did so just before installing Zone Alarm.

I thought I'd check out the logs of these attacks, and they all say they're originating from behind my firewall, 192.168.1.1, my computer. They're all UDP, and they're scanned in a sequential order from port 1024 to 65535. I know UDP packets are sessionless and used mainly for 'maintenance' or response/tracing. So, what exactly is going on?

Here's a sample of the log:
