I have installed Snort IDS and most alarm is:

"COMMUNITY SIP TCP/IP message flooding directed to SIP proxy"

And i use home DSL Internet connection , should i be worried about this alarm ?

I have read this article but i couldn't understand it completely?

I set firewall on my router and I've block WAN to LAN connections, how these kind of packet pass it inside ?!!

Is it possible that you are using an old snort version? Please see here: http://ubuntuforums.org/archive/index.php/t-1469108.html

Otherwise it would be great if you refine your question with some Firewallrules (Inbound) or some PCAP Files from wireshark.
