yeah, I've found that with (cisco pix 515e - CheckPoint) few weeks ago, i thought the problem was misconfiguration at that time, and even though the IPs were shown as 0.0.0.0, connectivity was achieved.

The destinations are every IP address on my public-DMZ. These are just HTTP Probes. This traffic is being dropped by my firewalls. Internal IDS does not show any of this event. Initially, I thought it was just normal scan, but since it is occurring everyday with that high frequency, I got more curious. However, I'm trying to understand what / how does the 0.0.0.0 Source mean. Could some of you kindly shed light on this fellow? I have googled it and done normal research.. but still not 100% clear. Is it something that we have mis-configuration? Is it broadcast traffic? Can I user my router to block this? .. all normal questions to defend my assets..
