Snort will not block sometimes.

  • I am running PfSense 2.1 and snort for IPS. every thing works perfect except every now and then snort will stop block alerts that I have set. It will show the alert but will not block. And then for no reason it will start blocking again.

    I am mainly using to block SIP attacks to my PBX. That is the only reason I caught it. I was going through the my logs and found an attack that happened a couple days ago so I check my snort records and it showed the attack but no block.

    Not sure what to do. Any advice? Thanks.

  • pfSense 2.1.* is no longer supported so you are running a really old version of Snort. Upgrade your pfSense and try again with the latest version of the package.
