Two or More Snorby Sensors on PFsense



  • I have a pfsense that acts as transparent. This pfsense receives the connections of two main segments of my network. One segment of the internet and another segment of the extranet. In both I have the snort set up doing the IDS / IPS work.

    I did the integration of these logs with SNORBY to have a better visual result when analyzing the logs. In a dedicated ubuntu machine I installed SNORBY and managed to integrate one of the interfaces with it. The problem is when I will configure the second interface. As far as I realize, to show the sensor in snorby I should set up the same snorby mysql database on the Barnyard2 tab of the interface in question. The problem is when I configure the same database settings for the second interface and restart snort on the interface, the barnyard2 configuration of the first interface drops, is unavailable.

    What I think is that it does not work to set up the same bank on both interfaces because it creates conflict. Something like that. But if I set up a second database, one for each interface, snorby will not recognize this second interface as there will be no association with the snorby flock.

    How can I solve this problem?

    My pfsense is:
