What were you trying to do that didn't work?

Use the portblock agent, but it fails to remove rules during stop-action due to a change in iptables -V output (it adds " (nf_tables)" after the version string).

E.g.

[root@rhel9-1 ~]# iptables -V
iptables v1.8.10 (nf_tables)

What is the impact of this issue to you?

Rule doesnt get removed during stop-action.

Please provide the package NVR for which the bug is seen:
