IPv6 无法在 Debian 11 上使用 nftables/nginx

我在 Debian 11 系统上运行带有 nftables 0.9.8 的 Web 服务器 (nginx 1.21.6)。我的 nftables 配置如下：

table inet filter {
chain input {
  type filter hook input priority filter; policy drop;
            ip saddr @spamhaus4 counter packets 0 bytes 0 drop
            ip6 saddr @spamhaus6 counter packets 0 bytes 0 drop
            meta l4proto tcp meta nfproto ipv4 ip saddr @abused counter packets 0 bytes 0 drop
            ip daddr 46.38.148.0-46.38.151.255 drop
            iif "lo" log group 2 accept
            iif != "lo" ip daddr 127.0.0.0/8 counter packets 0 bytes 0 drop comment "drop connections to loopback not coming from loopback"
            iif != "lo" ip6 daddr ::1 counter packets 0 bytes 0 drop comment "drop connections to loopback not coming from loopback"
            ct state established,related log group 2 accept
            ct state invalid counter packets 47 bytes 2572 drop
            tcp dport { 25, 80, 143, 443, 587, 2772, 9980, 45907 } log group 2 accept
            ip protocol icmp icmp type { echo-reply, destination-unreachable, echo-request, router-advertisement, router-solicitation, time-exceeded, parameter-problem } log group 2 accept
            ip6 nexthdr ipv6-icmp icmpv6 type { destination-unreachable, packet-too-big, time-exceeded, parameter-problem, echo-request, echo-reply, nd-router-solicit, nd-router-advert, nd-neighbor-solicit, nd-neighbor-advert, ind-neighbor-solicit, ind-neighbor-advert } log group 2 accept
            ip6 nexthdr ipv6-icmp log group 2 accept
            counter packets 2686 bytes 421604 drop
    }

    chain IPSinput {
            type filter hook input priority filter + 10; policy drop;
            counter packets 88448 bytes 15799025 queue num 0-3 bypass,fanout
    }

    chain forward {
            type filter hook forward priority filter; policy drop;
    }

    chain output {
            type filter hook output priority filter; policy accept;
    }

    chain IPSoutput {
            type filter hook output priority filter + 10; policy drop;
            counter packets 76196 bytes 201278628 queue num 0-3 bypass,fanout
    }
   }

nftables 防火墙运行良好。

但是，我的 nginx 服务器无法通过 IPv6 访问。我使用了不同的 IPv6 检查工具（例如，https://ipv6-test.com/validate.php） 并且Qualys ssl测试无法通过 IPv6 访问服务器，但 IPv4 可以正常工作。我已在每个 nginx 服务器中包括listen [::]:80;(resp.指令。并给出listen [::]:443;netstat -anlp |grep nginx

在我的路由器上，我也激活了 IPv6。

有人知道问题可能出在哪里吗？

感谢@Zoredache对我的问题的评论，我尝试 ping 我主机的 IPv6 地址。它只在我的家庭网络内有效。当我尝试通过子网在线或其他网站，它不起作用。

然后我在 unix.stackoverflow.com 上找到了这个答案：https://unix.stackexchange.com/a/443380/520989。我编辑了/etc/dhcpcd.conf文件并将其替换slaac private为slaac hwaddr。让我的路由器 (Fritzbox 7583) 忘记之前的配置并重新启动我的服务器，确实解决了我的问题！我的服务器现在可以通过 IPv6（也是 nginx）完全访问！
