So ok....trying to catch those naughty spammers using: alert tcp $SMTP_SERVERS 25 -> $EXTERNAL_NET any (msg:"Open Mail Relay Attempt"; content:"Relay access denied"; classtype:mail-abuse; sid:1000001; rev:1;) Now the above rule works. I originally had: alert tcp $EXTERNAL_NET any <- $SMTP_SERVERS 25 (msg:"Open Mail Relay Attempt"; content:"Relay access denied"; classtype:mail-abuse; sid:1000001; rev:1;) And it did not work. Any reason the two aren't equivalent?
Well logically they are.... The <- operator never really worked and was removed from the code. What version of Snort are you running? Recent versions should have said that the <- was invalid.
