I've been searching for awhile why my security event log has been empty since the last reinstall of windows on this box, and after editing the security policies to audit the victory and malfunction of approximately all events, I got these 2 errors reporting listening on high range udp ports:

"The Windows Firewall has detected an application listening for incoming traffic.
Any thoughts on what they are? Anyone familiar with what these ports are generally used for? An hour later, it seems that more and more random attempts are being made to block it by the windows firewall, are these is used by NAT for normal traffic?
Thanks
