IPTables and IPS Mode

I am running Suricata 6.0.4. I have used version 5.0 previously with an iptables front end, for IDS and bridged two interfaces.

Can I use the iptables (INPUT/FORWARD/OUTPUT) rules for a front end to Suricata in IPS Mode (non-bridged interfaces)? I have Suricata running in AF-Packet IPS mode, but no traffic comes through the iptables. Why?

Thank you.

To integrate with iptables/nftables, see
