After 5+ hours of WinDivert NETWORK-layer NAT-rewrite debugging
(streamdump pattern, SOCKET-layer SYN preemption, lazy PID resolution,
UDP ASSOCIATE relay + manual reinject), Discord voice still wouldn't
connect. The fundamental issue is that WinDivert reinjected UDP
packets don't always reach connect()-bound application sockets — the
demux happens at a layer above the reinject point.
dvp/force-proxy avoids this entirely via DLL injection (above the
kernel demux). We avoid it the other way: embed sing-box, let it run
TUN inbound + per-process routing rule + SOCKS5 outbound. TUN packets
are read by sing-box from kernel as a normal flow; the application
socket sees a normal flow back. No reinject hairpin, no SYN race, no
spoofing concerns.
What this commit does:
- Drops internal/divert, internal/engine, internal/redirect,
internal/socks5, internal/procscan, plus cmd/drover/{proxy,
debugflow}_*.go subcommands (all WinDivert-only).
- Adds internal/sboxrun — embed sing-box.exe (1.12.25) + wintun.dll
(0.14.1) via //go:embed, install to %PROGRAMDATA%\Drover\sboxrun\
with SHA256 verify, generate JSON config from form, spawn as
subprocess, manage lifecycle.
- Wires sboxrun into internal/gui/app.go: StartEngine/StopEngine
now call sboxrun.Engine instead of windivert engine.
- Fixes Wails binding: StartEngine(cfg) now passes the form config
(was zero-arg, hit ProxyHost-required validation silently).
Manual test: Discord chat + voice work end-to-end through mihomo
upstream. Yandex Music / svchost / etc continue direct via
process_name routing rule.
Binary grew from 12 MB → 49 MB (37 MB sing-box embedded), but ships
fully self-contained. AV-friendly: wintun is Microsoft-signed, no
DLL injection.
WinDivert work preserved on experimental/windivert branch in case we
ever want to come back to that path.

Drover-Go
Discord proxy / DPI bypass tool. Routes Discord traffic through a SOCKS5 proxy via kernel-level packet capture (WinDivert), bypassing the limitations of in-app proxy settings and surviving Discord auto-updates.
What it solves
Discord doesn't support proxies for voice/video traffic. Existing DLL-injection tools (drover, discord-voice-proxy) modify Discord.exe, which:
- triggers antivirus heuristics (unsigned DLL injecting into a popular app),
- breaks every time Discord auto-updates,
- doesn't proxy
Update.exeitself, so the updater fails when Discord servers are blocked.
Drover-Go uses WinDivert — a Microsoft-signed kernel driver — to capture packets at the network stack level. No modification of Discord, works for any Discord variant (Stable/Canary/PTB/Vesktop), survives auto-updates, minimal AV detection.
Status
Pre-alpha. See implementation plan for details.
How it works
Discord.exe (unmodified)
↓ TCP/UDP
WinDivert.sys (kernel filter)
↓ matched packets
drover.exe (Go)
├── TCP redirect to local SOCKS5 listener → SOCKS5 CONNECT → upstream proxy
└── UDP encapsulation (RFC 1928) → SOCKS5 UDP ASSOCIATE → upstream proxy
For UDP voice that's blocked even via SOCKS5 (DPI on the proxy's TCP control channel), drover-go injects a fake QUIC initial packet (à la zapret-discord-youtube) before forwarding — DPI sees "QUIC to Google" instead of Discord media.
Requirements
- Windows 10 1903+ or Windows 11 (x64). ARM64 not supported by WinDivert.
- Administrator privileges for first run (driver install).
- Upstream SOCKS5 proxy with UDP ASSOCIATE support (e.g.
mihomo,sing-box).
