nftables

RHEL 8 用 ntftable 替换 iptables,

新安装的 CentOS 8.3 是这样的：

[root@net182-host113 ~]# nft list tables
table ip filter
table ip6 filter
table bridge filter
table ip security
table ip raw
table ip mangle
table ip nat
table ip6 security
table ip6 raw
table ip6 mangle
table ip6 nat
table bridge nat

nft list ruleset
