RMC, If you are using 'var EXTERNAL_NET !$HOME_NET', then short should pass on everything defined in 'var HOME_NET blah' on that sensor. -Michael -- Michael Steele | System Engineer / Support Technician mailto:michaels () silicondefense com Silicon Defense: IDS solutions - http://www.silicondefense.com Snort: Open Source Network IDS - http://www.snort.org -----Original Message----- From: snort-users-admin () lists sourceforge net [mailto:snort-users-admin () lists sourceforge net] On Behalf Of Ralph Churchill Sent: Wednesday, January 22, 2003 12:14 PM To: snort-users () lists sourceforge net Subject: [Snort-users] $HOME_NET question 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? RMC __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
