退出 qBittorrent 后网络会轻微中断，求诊断~

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，即 13:14:13 至 13:57:06 翻查 qBittorrent 日志

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

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 测试工作量太大，所以先来请教一下大佬们，谢谢。

试试关闭 qbit 的 upnp
(手动在路由器里转发 qbit 端口流量)

UPNP 删除操作引起的短暂掉线（重联）。你可以在光猫里设置 DMZ 主机为你的电脑，你把你电脑 IP 改为固定内网（ IPV4 地址），关闭光猫 UPNP ，这样会比较稳定。

@MrGba2z @jousca 谢谢，我现在关掉 qBit 的 UPNP ，在路由器里手动做 IPv4 端口映射，我观察试试。

你这个光猫其实用的很老版本的 openwrt,bug 多，性能还差

@flynaj 这个光猫和 openwrt 有关系？后来我升级了光猫固件后就正常了，开启 UPnP 都正常。
