I set up Suricata in NFQUEUE with the following IPTABLES configuration:
 
Chain INPUT (policy ACCEPT 107K packets, 152M bytes)
 pkts bytes target     prot opt in     out     source               destination
 
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination
    0     0 NFQUEUE    all  --  p3p1   p2p1    0.0.0.0/0            0.0.0.0/0            NFQUEUE num 0
    0     0 NFQUEUE    all  --  p2p1   p3p1    0.0.0.0/0            0.0.0.0/0            NFQUEUE num 0
    0     0 NFQUEUE    all  --  p1p1   eth0    0.0.0.0/0            0.0.0.0/0            NFQUEUE num 0
    0     0 NFQUEUE    all  --  eth0   p1p1    0.0.0.0/0            0.0.0.0/0            NFQUEUE num 0
 
Chain OUTPUT (policy ACCEPT 65421 packets, 3998K bytes)
 pkts bytes target     prot opt in     out     source               destination
 
and 
 
suricata -v -c /etc/suricata/suricata.yaml -q 0
 
and all traffic come to a halt.  What am I doing wrong?
