Suricata not working at all



  • I've been trying to get Suricata to work after migrating to a new box. Currently it's set to use inline mode which should be supported on the Intel I211 interfaces I'm using. I've also tried using Legacy mode as well but without avail.
    The process itself starts and stays up stable without problems on two interfaces (WAN and VPN) but no alerts are being generated. This is the log output of the WAN instance:

    Anyone else experiences something similar and could point me to the right direction=



  • Suricata and Snort both depend on the values of the HOME_NET and EXTERNAL_NET variables being set correctly.  Many of the rules from both the VRT and Emerging Threats uses HOME_NET and EXTERNAL_NET as source and destination values for IP addresses.

    If the IP addresses in HOME_NET and EXTERNAL_NET are not correct, many rules will fail to trigger and fire alerts because all of the "conditions" for triggering are not met.  So first question would be have you modified any of the defaults for HOME_NET or EXTERNAL_NET?  If you are trying to monitor a VPN, it could be the IP addresses of the VPN tunnel are not getting properly placed in HOME_NET.  In that case, you would need to create a Pass List and use it as a customized HOME_NET.
