hai, I've been dealing with this for a while. I want to know if I'm doing something wrong or if it's a bug in Snort. I'm running snort sensor(1.8.7) on RedHat7.3. My snort.conf: $HOME_NET [xx,xx,xx,xx/24,yy,yy,yy,yy/24,and a few more] $EXTERNAL_NET !$HOME_NET. If I write a alert: alert tcp $HOME_NET any -> $EXTERNAL_NET any (msg:"bla";) This rule will also catch traffic from my internal net to my internal net, and I will get too much false positives. But if i write it like below: alert tcp $HOME_NET any -> !$HOME_NET any (msg:"bla";) it won't catch it. Is this a bug in snort if you have multiple subnets in your HOME_NET. Please help me, __________________________________________________ Do you Yahoo!?
