See attached. I just tested it with the -T and it runs fine. This is the sample (trimmed down config I used with your variables). # Setup the network addresses you are protecting ipvar HOME_NET 192.168.10.0/24 # Set up the external network addresses.

On /etc/snort/snort.conf i have set the EXTERNAL NET as any. I tried to make as !$HOME NET, but then the snort fails to load at startup. If i change it back to any everything works fine. How else can i avoid receiving alerts from my internal network?

what is the exact error message given at startup when you set EXTERNAL_NET to !HOME_NET?? -- NOTE: No off-list assistance is given without prior approval. *Please keep mailing list traffic on the list* unless private contact is specifically requested and granted. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Snort-users mailing list Snort-users () lists sourceforge net<mailto:Snort-users () lists sourceforge net> Go to this URL to change user options or unsubscribe: https://lists.sourceforge.net/lists/listinfo/snort-users Snort-users list archive: http://sourceforge.net/mailarchive/forum.php?forum_name=snort-users Please visit http://blog.snort.org to stay current on all the latest Snort news!
