A highly-optimized, lightweight Realtime Connection Tracking & Network Audit Monitor for OpenWrt/LEDE. This plugin provides single-direction (TX/RX split), high-frequency, millisecond-level traffic visualization directly within the LuCI web interface.

• Zero Kernel Contamination (No kmod): Unlike legacy traffic accounting tools, it does not inject any custom hooks or proprietary kernel modules. It fully leverages the Linux native /proc/net/nf_conntrack subsystem—data that the kernel already maintains for NAT routing—guaranteeing zero system pollution and maximum stability.
• UI Features:
  • Realtime Connection Speed: Displays instant throughput for each traffic direction in real time.
  • Bit / B Unit Toggling: Seamlessly switch between Bit (bps/Mbps) and B (B/s/MB/s) locally via JS without dropping the SSE pipeline.
  • Original/Reply Traffic Splitting: Tears apart conntrack rows to display precise directional analytics (TX/RX isolation).
  • QUIC/HTTP3 Recognition: Automatically sniffs out modern HTTP/3 streams via UDP 443 heuristic auditing.
  • IPv4/v6 double stacks supported.
  • Adaptive Layout with Tooltips: Prevents UI breakage from long IPv6 addresses using CSS ellipsis combined with native hover tooltips.
  • Specific IP / Local & Loopback IP filter supported.
  • Local host name supported.
  • GeoIP info supported.
  • Experiment feature Show app name(YouTube, Instagram, TikTok, etc.) associated with the connection, this will need to patch kmod-nf-conntrack (patch file: 999-netfilter-custom-payload-telemetry-nf_conntrack.patch).
  • Cutomized App Icons*

一款为 OpenWrt/LEDE 深度定制、工业级稳定的实时连接跟踪与单向流量审计看板。该插件完全基于轻量级的 Event-Stream (SSE) 长连接架构下运行，无需刷新页面即可在 Web 界面实现真正高频、正反向物理隔离的网络吞吐审计。

• 零内核污染 (无需 kmod)： 不同于传统流量统计插件需要往内核安插臃肿的探针或第三方驱动，本插件完全基于 Linux 内核原生维护的 /proc/net/nf_conntrack（连接跟踪表）作为数据源。对系统内核零开销、零污染，保障极限负载下的系统稳定性。
• UI 特性：
  • 实时连接速率： 高频显示每一条活跃网络连接当前的实时瞬时物理吞吐速率。
  • 前端零延迟单位切换： 表头集成智能交互按钮，支持在 Bit（比特率，Mbps）和 B（字节率，MB/s）之间 1 毫秒无缝切换，无需掐断或重启后台长连接。
  • 正反单向流量分离： 将 conntrack 报文拆分为 Original（发起方）与 Reply（回应方），实现真正的单向 TX/RX 独立审计与降序排列。
  • QUIC / HTTP3 智能识别： 基于启发式行为审计，自动将隐藏在 UDP 443 端口下的现代高并发视频/下载流标记并显示为 QUIC 协议。
  • IPv4/v6 双栈支持
  • 超长 IPv6 弹性布局： 引入 CSS 精确截断裁切，使超长 IPv6 地址自动变为省略号，鼠标悬停时原生 Tooltip 气泡自动浮现完整内容，排版永不撑破。
  • 手动指定IP或本地以及回环IP 过滤支持
  • 本地主机名显示支持
  • 地理IP信息显示支持
  • 实验特色 显示与连接相关的应用名称(YouTube, Instagram, TikTok, 王者荣耀..), 你需要给内核模块 kmod-nf-conntrack 打补丁 (补丁文件: 999-netfilter-custom-payload-telemetry-nf_conntrack.patch).
  • ** 定制化App图标库 **
