Public bug reported: >From my lab, I tried to apply the stateless securigty group for one port "172.26.9.54" and use hping3 to generate tcp connections and monitor the nf_conntrack number but nothing is effect. After debug in iptables rules, I saw the following syntax error in iptables caused the "no- track" policy to become ineffective:
