Listener on 127.0.0.1 accepts NAT-rewritten Discord SYNs (rewrite done by divert layer in Task 10), looks up the original destination in a sync-protected map keyed by source port, opens a SOCKS5 CONNECT to the upstream proxy targeting that destination, and pumps bytes both directions until either side closes. 30-minute TTL sweeper handles T-6 in the edge case matrix (mapping leak when a flow never properly closes). Pump teardown: when one direction's io.Copy exits, the goroutine CloseWrite's its write side AND sets a past read deadline on the OTHER conn so the peer goroutine's blocked read unwinds promptly even when the upstream half never sends EOF (test fake-SOCKS5 hits this; the real upstream may too).

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).
