用的是B610-4E光猫拨号，开启IPv6，光猫配置如下：

硬件版本：1B40.A
软件版本：V5R019C20S190


wan配置


DHCPv6配置

Windows 11 + qBittorrent 4.5.2，种子数5000+，活动状态（正在产生上传或下载流量）种子数30~50左右，具体症状为：退出qBittorrent后（退出前已停止所有正在活动的种子），网络会出现轻微中断，比如本机运行的ToDesk和向日葵大概率会变灰（即连不上服务器），但很快又能重新连上；比如局域网内另一台设备访问获取公网IPv6串流会出现断流，也是重新连接就能恢复正常，但过一会儿又有概率再次断流。

查看光猫调试日志，发现log里面自从光猫上一次重启后，正是在退出qBittorrent后，才产生了新的日志记录。光猫日志如下（不含光猫重启初始化阶段）：

192.168.100.88是我运行qBittorrent的设备IP，日志时间需要+8转换为本地时间；upnp服务就只有qBit和zerotier，但日志里面的upnp记录应该和zerotier无关，毕竟退出qBit前也没见相关记录。
翻查qBittorrent日志

1. (N) 2023-05-01T13:14:29 - 发起了 qBittorrent 终止操作
   
2. (I) 2023-05-01T13:14:29 - UPnP/NAT-PMP support: OFF
   
3. (N) 2023-05-01T13:22:37 - qBittorrent 现在准备好退出了

复制代码

我是在13:06-13:14期间对活动种子执行停止操作，13:14执行退出qB指令，13:22完成qB退出。

求高手帮忙诊断一下，我这问题是出在哪呢？是光猫没配置好还是qB的软件问题？种子数太多如果换另一个BitTorrent测试工程量太大，所以先来请教一下大佬们，谢谢。

可能就是退出时候为了同步上传量汇报了所有种子的tracker，因为种子多瞬间突发连接数爆炸。排除法就是暂停剩100个种子做种，然后退出看看卡不卡，估计瓶颈在B610的最大连接数上吧

但qBit日志显示qBit在13:22已经完全退出了，应该就是完成了所有的tracker汇报后才完全退出的。但B610日志显示在05:22后仍持续产生多条日志，[Debug][Debug-Log] static:[dhcpd]send Ack 这些记录貌似和断连的时间点对上了。

开fullcone或者DMZ试试。

玩P2P和PCDN的，光猫还是桥接吧，直接上硬路由跑。

我截图上NAT类型“完全锥形NAT”就是fullcone吧？B610也是一个硬路由吧

完全锥形NAT改成受限试试，我之前HS8145V这个选项容易造成重启

膜拜LZ 保种5000+ 。。。 我挂500个种子 QT 就反应慢的一批了

虽然觉得是qBittorrent的退出机制有问题。

也可以把b610固件190更新到210试试，据说修了一些bug。
直接web更新就行。

我的b610直接升级了没有问题。

谢谢，我之前一直不敢补全shell和升级固件，这次正好试试，补全shell和升级固件成功，观察一下。

建议不要光猫拨号，直接电脑连光猫电脑拨号试试情况如何？

感谢大佬，更新到210固件后正常了。

Hmmm....  后面qBittorrent更新到v4.5.4版本后，退出又有断流问题了……

我买的是那个B610-S1-4E，好像没得刷，就当个普通光猫桥接，iptv拨号而已，目前稳定，之前那个华为8145V6内存bug一直解决不了，就换了
