Tor transport for Mirror Networking as a .onion hidden service.

Mirror Tor Transport

A Unity transport layer for Mirror Networking that routes connections through Tor, allowing anyone to connect anonymously via a .onion address.

How it works

Instead of connecting directly, the client performs a SOCKS5 handshake through the local Tor proxy before handing the connected socket to Mirror. The server runs as a Tor hidden service, getting a .onion address that players use to connect.

Requirements

• Unity 2021.3.45f2
• Mirror Networking 86.12.2
• Tor running locally on 127.0.0.1:9050

Installation

Windows:

• Install Tor standalone via Expert Bundle
• Add torrc config file: SocksPort 9050 | ControlPort 9051 | DataDirectory tor_data | HiddenServiceDir C:\Tor\hidden\ | HiddenServiceVersion 3 | HiddenServicePort 7777 127.0.0.1:7777
• Run .\tor.exe -f torrc

Unity:

• Install Mirror 86.12.2
• Copy the TOR/ folder into your Assets
• Replace TelepathyTransport on your NetworkManager with TorTelepathyTransport
• Add UnityMainThreadDispatcher component to your NetworkManager GameObject
• Use Net/ folder for conn tests

Usage

Hosting:

• Run Tor as a hidden service pointing to port 7777
• Share the generated .onion address with players

Connecting:

• Make sure Tor is running on port 9050
• Enter the .onion address and connect

Latency expectations

Tor routes through 3 relays worldwide so expect 400-800ms RTT.
