Ordering Rich Rules With Firewalld

Is there any way to order rich rules in firewalld? If I remove all rules and add them back in firewalld seems to put them in whatever order it feels like.

Alternatively, how can I change the default policy of a firewalld zone?
At the moment I don’t see any way to have a zone accept traffic by default other than adding a rich rule allowing 0.0.0.0/0.

  • Requesting any features should go to either RedHat, as CentOS, crudely stated, is “binary replica” of RedHat Enterprise” Linux. Or to open source firewalld project:

    I hope, this helps.

  • How about 
    http://www.firewalld.org/documentation   -> firewall.direct(5)

    priority=”priority”
    The priority is used to order rules. Priority 0 means add rule on top of the chain, with a higher priority the rule will be added further down. Rules with the same priority are on the same level and the order of these rules is not fixed and may change. If you want to make sure that a rule will be added after another one, use a low priority for the first and a higher for the following.

    Sounds like the way to force the order.

  • I believe the priority feature is introduced in a version later than what is in CentOS 7. However, I believe the 7.3 update (in beta now for RHEL) has a version that supports priority.

  • i’m on CentOS Linux release 7.2.1511 (Core) and firewalld 0.3.9
    and it works, has been for a few months, perfectly fine.
