上海电信无法获取 ipv6，原生拨号或桥接都不行

前景：
家里使用上海电信从 08 年至今，从最初的 30Mbps 套餐到目前 399 （实际 199 ）套餐 2Gbps 下行、300Mbps 上行，每月 450G 5G 流量。
光猫是中兴 G7615V2 ，桥接模式，路由设备使用畅网 P5-N100 ，PVE 虚了 ros ，4 网卡直通给 ros 。
前两天出现公网 ip 突然被回收的情况，10000 号投诉后装维给重新申请了公网 ip

日常使用场景：
家里正常上网需求，在公司使用畅网 N100 开发版

全程 WG 回家上网，家里 ROS 默认上海电信、香港、新加坡、日本多出口

问题：
最近公司同事提了个测试需求，希望有 ipv6 出口，但公司目前只有 ipv4 ，这个小需求也懒得让同事去推动公司增加 ipv6 了。于是开始尝试在 ROS 中打开 ipv6 ，公司测试 ipv6 就接入 N100 开发版 wg 回家。

经过半天的折腾，查了整个互联网 ROS 开启 ipv6 的资料，ipv6 dhcp 始终显示 Searching 。
1：ros 版本也升级至最新关闭了 Vaildate Server DUID 。
2：ROS AC NAME 尝试绑定 SH-SH-JDMYQJ-MSE-1.MAN.M6000/SH-SH-LN-VBASCP-1.NMAN.V6000 均无效。
3：怀疑过需要打开 PVE 支持 IPV6 ，无效。
4：找装维后台查过确认是 ipv4/ipv6 双栈（目前还抱有怀疑，原因后面说）
5：ipv6 防火墙允许 ipv6


ROS 相关 ipv6 日志如下

实在查不到原因
开始直接 mac 接光猫 pppoe 拨号也是拿不到 ipv6

继续尝试关闭桥接使用原生光猫路由模式发现仍然无法获取 ipv6 ，具体如图

光猫中各种配置如图



下图中 地址获取方式、前缀获取方式、dns 获取方式均尝试过各种配置无效




光猫桥接配置



因为使用光猫原生拨号都未拿到 ipv6 配置且状态显示不可用，开始怀疑电信后台是否真的为我开启了 ipv6 ，电话询问装维他们是否有设备上门直接测试 ipv6 ，回答目前没有设备支持测试且说目前 ipv6 仍未大规模开放实行，意思让我就用 ipv4 得了。建议让我使用第三方路由器拨号尝试，说之前也有个客户拿不到 ipv6 ，后来用了华硕路由器拨号成功拿到了 ipv6 配置，我心想这不是典型忽悠我么。明天准备继续电话装维让后台的人联系我看看问题出在哪里。
