Hello, I have many problems with snort, for example some rules work fine and others don't work. But what surprises me a lot is that snort only alert about rules with my IP (where snort is installed) as source or destination . I've tried with this rule: alert tcp any any -> any any (msg:"TCP traffic";sid:1000011; rev:1;) The only alerts registrated are those which have my IP. I don't understang anything. I have this information in snort.conf: *var HOME_NET 172.18.64.0/19* var EXTERNAL_NET any var DNS_SERVERS $HOME_NET var SMTP_SERVERS $HOME_NET var HTTP_SERVERS $HOME_NET var SQL_SERVERS $HOME_NET var TELNET_SERVERS $HOME_NET var SNMP_SERVERS $HOME_NET Snort is installed in 172.18.65.16. There are many others IPs availables in my network. Other rare thing, I changed $EXTERNAL_NET to any in a rule and then it worked, but I have rules with $EXTERNAL_NET that work fine. (I use Windows XP+Snort 2.7+Base) Thank you very much for any idea
