nostr:npub1upkp7fd7rc3lrjg23r8gy0wc723vze7mxlx5984ut6zurjzpf5xss4tcwy From what I remember, we moved to other forms of port management when changing iptables required too much potential breakage. (nftables, e.g.)

I think some distros, instead, just put wrappers around iptables rather than use the new stuff (e.g. I think ufw was/is just a front end that works with both ptables nftables?)

Take that with a grain of salt, because I've been using firewalld and ufw almost exclusively for over a decade, because they were always "good enough".
