📄️ Simple Stateful Firewall
Configure a Simple Stateful Firewall with nftables.
nftables is the modern Linux kernel packet classification framework. New code should use it instead of the legacy {ip,ip6,arp,eb}_tables (xtables) infrastructure. For existing codebases that have not yet converted, the legacy xtables infrastructure is still maintained as of 2021. Automated tools assist the xtables to nftables conversion process.
