[Athens Yan]

Package: firewalld
Version: 0.6.3-5
Severity: important

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate
***

   * What led up to the situation?
     After add new rules to firewalld, and then reload it, error messages
are displayed and firewalld mulfunction.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
     I run the following commands in super user mode:
     firewall-cmd --zone=public --permanent --add-service=ssh
     firewall-cmd --zone=public --permanent --add-service=http
     firewall-cmd --zone=public --permanent --add-service=https
     firewall-cmd --zone=public --permanent --add-icmp-block=echo-request
     firewall-cmd --reload

   * What was the outcome of this action?
     Error messages show up as follows:
     Error: COMMAND_FAILED: '/usr/sbin/ip6tables-restore -w -n' failed:
ip6tables-restore v1.8.2 (nf_tables):
     line 4: RULE_REPLACE failed (No such file or directory): rule in chain
OUTPUT

     After that, I run command 'firewall-cmd --list-all', error message
'Error: INVALID_ZONE' is seem.

   * What outcome did you expect instead?
     New firewall rules can be added, and firewalld functions normally.
