How is to add port number into "ports" port list?
(If you gets alerts for specific port(s).)

Or if you are assured that the alerts means no security risk, you can
suppress alert message.

For example, write local rules like:
suppress gen_id 129, sig_id 12, track by_dst, ip XX.XX.XX.XX
suppress gen_id 129, sig_id 12, track by_src, ip XX.XX.XX.XX

BTW, I am using Snort for Linux and Widows PC (XP SP3).
On Win XP (with wireless network), device sometimes hangs up after
small segment alert. I am not sure that small segments causes it or
Device revives after reconnecting to access point.

Is there any solution?

(Snort: 2.9.3, WinPcap: 4.1.2)
