I an using a dlink router to connect two computers to my cable modem. One computer is running ZA free and the other is running ZA Extreme. The computer running ZA Extreme seems to be under attack as there are attempts to access ports continually. Every 10 seconds there is around 20 attempts to access the ports by access attempts on sequential port numbers. The computer running ZA free has none of these alerts in the logs and seems to be fine.

Here is an example of my current ZA extreme log -
