Вопрос Не получается настроить NFtables на своей VDS

[Art_Farm]

Хотел настроить nftables для доп защиты своей vds, вот конфиг /etc/nftables.conf:

table inet filter {
    chain prerouting {
        type filter hook prerouting priority -150; policy accept;
        tcp option maxseg size set rt mtu
    }

    chain input {
        type filter hook input priority 0; policy drop;
        ip saddr 127.0.0.0/8 accept
        ip6 saddr ::1/128 accept
        ct state invalid drop
        ct state established,related accept
        tcp dport 22 ct state new,established accept
        ip protocol icmp icmp type echo-request accept
        icmpv6 type echo-request accept
        meta length > 1500 drop
        log prefix "INPUT_DROP: " limit rate 10/minute
        counter
        drop
    }
}

Вроде всё верно, да и модули я все установил.
Но при вводе «nft -c -f /etc/nftables.conf» ошибка:
