## What it is
Gnirehtet provides reverse tethering for Android devices over adb, letting a plugged-in phone use the computer's internet connection without root access. It ships as a Rust relay server (recommended) with a Java alternative, plus an Android VPN client app.

## Use cases
- share my PC's internet connection with my Android phone over USB
- reverse tether Android without root
- give an Android device network access when Wi-Fi is unavailable
- test an Android app against a controlled desktop internet connection
- relay TCP and UDP traffic from Android to a computer via adb

## When to choose
- you need reverse tethering on Linux, Windows, or macOS without rooting the device
- you want a lightweight native tool (Rust) with no Java runtime dependency
- you need IPv4 TCP/UDP relay over adb for Android 5.0+

## When to avoid
- you need IPv6 support, which is not implemented
- you want actively developed software with new features
- you need wireless tethering rather than a USB/adb connection
