Filed under
Software

Firewalld was started by Red Hat a decade ago for managing Linux firewall functionality with Netfilter. Ten and a half years after the first release, Firewalld 1.0 was released this afternoon.

Firewalld 1.0 comes with breaking changes including dropping of Python 2 support, other dependency changes, support for intra-zone forwarding by default, NAT rules being moved to iNet family, the default target now being similar to reject, deprecating the older IPTables back-end, and more.

Firewalld 1.0 Firewall Management Tool is Here...

  • Firewalld 1.0 Firewall Management Tool is Here with Big Improvements

    Ten years after its first release, Firewalld reached version 1.0. The biggest change is removing Python 2 support.

    Firewalld is front-end controller for iptables and nftables used to implement persistent network traffic rules. It provides command line and graphical interfaces and is available in the repositories of most Linux distributions. The name Firewalld adheres to the Unix convention of naming system daemons by appending the leter “d”.

    Firewalld is easier to manage and configure than iptables. It offer a very flexible way to handle the firewall management compared to iptables. There are no long series of chains, jumps, accepts and denies that you need to memorize to get Firewalld up and running. It manages rulesets dynamically, allowing updates without breaking existing sessions and connections. Changes can be done immediately in the runtime environment. No restart of the service or daemon is needed.

  • Firewalld 1.0: Red Hat modernizes firewall configuration on Linux

    Many 0.xx versions of Firewalld have accumulated over the years. With version 1.0 of the tool for network firewall configuration under Linux, Red Hat is now cutting old threads and reducing dependencies. The new version is no longer compatible with Python 2. In addition, the project declares Direct Interface and the PTables backend to be out of date. We have also said goodbye to the tftp client service.

    The upcoming release also raises intra-zone forwarding to the standard. By moving the NAT rules to the iNet family, the rule set is reduced. The default target is now similar to reject. ICMP blocks and block reversal are now only valid for input and not for forwarding. CleanupModulesOnExit is set to no by default and kernel modules are not unloaded.
