If I have my home net of snort set to: var HOME_NET [10.215.0.0/16] How can I make my external net be !$HOME_NET and 10.215.40.0/24 subnet?
if i'm reading that right, then your HOME_NET is incorrect if 10.215.40.0/24 is not part of it... the following make up the 10.215.0.0/16 network without 10.215.40.0/24 in it... the numbers in parenthesis are the range of addresses in that CIDR... 10.215.0.0/19 (10.215.0.0 - 10.215.31.255) 10.215.32.0/21 (10.215.32.0 - 10.215.39.255) 10.215.41.0/24 (10.215.41.0 - 10.215.41.255) 10.215.42.0/23 (10.215.42.0 - 10.215.43.255) 10.215.44.0/22 (10.215.44.0 - 10.215.47.255) 10.215.48.0/20 (10.215.48.0 - 10.215.63.255) 10.215.64.0/18 (10.215.64.0 - 10.215.127.255) 10.215.128.0/17 (10.215.128.0 - 10.215.255.255) so you would have your HOME_NET set like this... var HOME_NET [10.215.0.0/19, 10.215.32.0/21, 10.215.41.0/24, 10.215.42.0/23, 10.215.44.0/22, 10.215.48.0/20, 10.215.64.0/18, 10.215.128.0/17] and then your external net would be !HOME_NET because 10.215.40.0/24 is already not listed as part of your home network ;) ------------------------------------------------------------------------------ This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.
