我使用的是 CentOs 8。这是我的 ifconfig:

我打开了路由器(fritz.box)上所有需要的端口并设置了默认的 ipv6 接口 id749e:eeb5:cad4:3ff8
当我fe80::6203:7858:3288:57d1
从另一个设备 ping(本地 ipv6 ip)时我得到了信息,但是当我 ping 2001:16b8:2ad6:8e00:749e:eeb5:cad4:3ff8
- 这应该是一个公共 IP 时,我没有得到任何信息回报。我的防火墙已关闭并且 IPV6 已启用。
有人可以指出我正确的方向吗?谢谢阅读
答案1
您必须在相关主机的防火墙规则中允许 Ping6。我使用 Fritz!Box 7490(互联网/Freigaben -> 主机)
ICMP 不使用端口。您不必设置接口 ID。
如果您选择一个主机来编辑防火墙规则,FB 会显示该主机的接口 ID。这样您就可以检查是否为正确的主机添加了规则。 “全局动态 mngtmpaddr”IPv6 地址是您可以从外部 ping 通的地址。至少如果该主机上没有防火墙规则阻止“icmp echo requests”->使用firewall-cmd --list-all并检查“icmp-blocks:”
