数据结构:nftables 使用基于内核空间的数据结构,而 iptables 使用链表数据结构。nftables 的数据结构更加高效,可以更快地进行匹配和查找操作。 语法:nftables 的配置语法更加简洁和直观,支持类似于 C 语言的语法。而 iptables 的配置语法相对复杂,使用起来可能会更加困难。 性能:nftables 在处理大规模规则时性能更好,可以...

(again due to netfilter) if there are multiple chains attached to the same hook - it's not as simple as iptables vs nftables. There are a handful of options to workaround theACCEPTissue: 1. Rich Rules If a rich rule can be used, then they should always be preferred over direct rules...
