While testing my network security on one of my Windows 7 PCs, I enabled all the firewall event logging and then performed a series of port scans from another PC on my network running Ubuntu Linux. I used the program nmap to perform specific ICMP pings, but none of them registered in the Inbound Events section of the Internet & Network event log. Interestingly, my other Windows 7 computers' ICMP periodic pings (from the Windows 7 homegroup services) do show up in the log.
Here is the actual tests I've performed and their results, which clearly show that the defending computer (192.168.1.82) responded to these inbound events even though they did not get logged.

FYI the -PP and -PM arguments to nmap perform adress and timestamp ICMP requests, respectively. Note that my linux box's IPv4 is : 192.168.1.148 and its IPv6 is : fe80::21c:bfff:fe56:1227/64
Could this issue be related to the fact that my McAfee event log seems to log all events in IPv6 format whereas my linux box is accessing it from IPv4? If so, how can I force McAfee to log IPv4 events?
Any ideas anyone? I still can't figure this one out...
