<div dir="ltr">Ok, so we found our problem. Turns out that kernel 4.13.4-1.elrepo.x86_64 does not work with Suricata for af_packet fanout. By downgrading to kernel 4.12.8-1.elrepo.x86_64, this worked again. Please advise as to why this kernel does not seem to work. It properly fans out for Bro, so it seems to be something specific to Suri.
