I just checked the suricata.yaml file from the GIT repo... the
EXTERNAL_NET: any doesn't have any quotes... However, if you want to change
it to something other than any, put the quotes around it...
ie: EXTERNAL_NET: !$HOME_NET
should actually be:
EXTERNAL_NET: "!$HOME_NET"
Somebody should put a note in the .yaml file somewhere!
See Yas!
