I have snort 1.8.7. I have set my $HOME_NET to be $eth0_ADDRESS and my external net set to !$HOME_NET. However, I still get alerts from other computers on my subnet! For example, the "SNMP public access udp" rule says: alert udp $EXTERNAL_NET any -> $HOME_NET 161... For this example, assume my IP is 192.168.1.2. I'm getting alerts for a packet from 172.20.39.32 to 192.168.1.3. Why? I'm totally confused. I thought $HOME, if set to $eth0_ADDRESS would only give alerts for things coming into my IP?!?! Am I wrong?
Depends. Where are the alerts coming from? From rules or from one of the preprocessors? Can you post a copy of the error? Can you post your HOME_NET statement? ----- Erek Adams "When things get weird, the weird turn pro." H.S.
