It depends where you are attaching your IFB device. Unlike IMQ, IFB can
only be hooked on an interface (IMQ can be hooked between iptables
chains). Therefore, if you are doing it on the ingress interface,
traffic will not have been connection-tracked. Off the top of my head,
it should work on egress though.
