as you have configured nfqueue=2, do you have setup 

ips_queues: 2

?

Objet: [PVE-User] Proxmox Suricata Setup

Hi, 
I've followed the instructions for setting up Suricata on my Proxmox server as detailed at:https://pve.proxmox.com/wiki/Firewall 

However, no traffic is currently being filtered by Suricata to or from the VMs or containers (dns, http, fast logs show nothing). 
My /etc/default/suricata is: 
RUN=yesSURCONF=/etc/suricata/suricata.yaml 
LISTENMODE=nfqueue 
IFACE=eth0 
NFQUEUE=2TCMALLOC="YES"PIDFILE=/var/run/suricata.pid 
I have a OVS bond (bond0) setup with an OVS bridge (vmbr0) for the public interface. 
I've had to override the default Suricata systemd configuration in order to run the Suricata init script & thus the /etc/default/suricata configuration using the following: 
[Service]ExecStart=ExecStart=/etc/init.d/suricata startExecStop=ExecStop=/etc/init.d/suricata stop
