Snort Blocking



  • Hello Everyone,

    I have recently switched to pfSnese from IPCop.  I am loving the change so far!

    I have configured Snort with blocking on my firewall.  I would like to exclude some rules from automatic blocking.  Some rules, such as the Shellcode ones generate quite a bit of false positives in my implementation.  I am not able to find a way to do this in the GUI.  The host whitelist feature won't work for me because there are too many.  I also don't want to suppress the noisy rules because I would like to see the alerts and investigate manually.  I was going to edit the configuration files and was hoping that someone can point me in the right direction.  My questions are:

    1.  Which snort.conf does the Snort package use in pfSense?  I have two, /usr/local/etc/snort/snort.conf and /usr/local/etc/snort/snort_14918_bge0/snort.conf?

    2. This directive seems to be ignored:  portvar SHELLCODE_PORTS !80.  Does pfSense not use this VAR or is there something wrong with my config?

    3.  Where does pfSense configure blocking in Snort?

    Thanks in advance!
