能分享服务器的防火墙配置吗？

table inet dev {

  set blackhole_ipv4 {
    type ipv4_addr;
    flags dynamic, timeout;
    size 65536;
  }
  set blackhole_ipv6 {
    type ipv6_addr;
    flags dynamic, timeout;
    size 65536;
  }

  chain input {
    type filter hook input priority filter; policy accept;

    ct state new tcp dport 22 limit rate 10/hour

    ct state new tcp dport 443 \
        meter flood_ipv4 size 128000 { ip saddr timeout 10s limit rate over 10/second } \
        add @blackhole_ipv4 { ip saddr timeout 10m }
    ct state new tcp dport 443 \
        meter flood_ipv6 size 128000 { ip6 saddr and ffff:ffff:ffff:ffff:: timeout 10s limit rate over 10/second } \
        add @blackhole_ipv6 { ip6 saddr and ffff:ffff:ffff:ffff:: timeout 10m }

    ip saddr @blackhole_ipv4 counter drop
    ip6 saddr and ffff:ffff:ffff:ffff:: @blackhole_ipv6 counter drop
  }
}
