Since I last posted here I ended up formatting my hard drive, installing
the latest Ubuntu and installing Snort in IPS mode. However, at the end
of the tutorial on
http://sublimerobots.com/2016/02/snort-ips-inline-mode-on-ubuntu/ it
shows you how to modify the single local rule to drop rather than alert.
There is mention of a future page that will tell how to have Pulledpork
automatically modify all the rules to drop.

My setup is running in inline mode but so far hasn't reported any
packets being flagged. I could sure use some help.

Thanks,

Jim

James,

Thanks for the reply and the pointer to the site. Those instructions
would allow me to drop specific rules. What I wanted to do is to drop
any packet that alerted, then except specific rules that I want to
allow. Something like the inverse of what your site specified. I did
some searching on the internet and found the following site:

https://s3.amazonaws.com/snort-org-site/production/
document_files/files/000/000/013/original/Snort_IPS_using_DAQ_AFPacket.pdf

I realize that my original question specified Pulledpork. I wasn't aware
that Snort being properly configured could do IPS all by itself. Snort
is now doing what I want it to do.

Thanks again,

Jim
