I'm experiencing what I believe to be a false positive on the BO2K-UDP (4055) signature. As near as I can tell, it is getting triggered by Xbox consoles when they connect to the Xbox Live! service. I am currently running the S307 sig update. What is the best way to report this to get it fixed?
I ran into this one too. After I looked at things, it is IPsec VPN traffic which triggered it. It was getting fired when traffic went to the outside interface of the PIX (not ASA). The PIX is also does remote user VPN traffic.
