I just checked and nftables is now the backend to firewalld. I think this happened awhile ago. A quick google search said it happened around version 0.6 of firewalld. Indeed, the man page for firewalld.conf states: FirewallBackend Selects the firewall backend implementation. Possible values are; nftables (default), or iptables. This applies to all firewalld primitives. The only exception is direct and passthrough rules which always use the traditional iptables, ip6tables, and ebtables backends. Time to explore the nft command. :-) -- The key to getting good answers is to ask good questions. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
