Hi all,

 Finally I have a snort_inline 2.8.2.1 sensor with nfqueue support 
installed on my laptop and integrated with ossec ...

 But I have two questions:

 - Some recommendations about kernel params like Victor Julien publish 
in his blog: 
http://www.inliniac.net/blog/2008/01/23/improving-snort_inlines-nfq-performance.html??
 


 - And a funcionality question: sometimes appears in snort's alert log 
entries like this:

 [**] [116:150:1] (snort decoder) Bad Traffic Loopback IP [**]
[Priority: 3]
07/04-17:44:56.578830 127.0.0.1:55363 -> 127.0.0.1:25
TCP TTL:240 TOS:0x10 ID:0 IpLen:20 DgmLen:46
***AP*** Seq: 0x2CB755E  Ack: 0x339A7A9  Win: 0x8480  TcpLen: 20

 This alert is relative to my postfix local smtp server ... How can I 
disable this type of alerts (only for 127.0.0.1 ip)??

Many thanks to all ...

Please any hints??
