Port Forwarder

A simple IPv6-compatible port forwarding tool written in Rust.

Features

• Supports both IPv4 and IPv6
• Forward and reverse proxy modes
• Asynchronous I/O with Tokio

Installation

1. Install Rust from https://www.rust-lang.org/tools/install
2. Clone this repository
3. Run cargo build --release

Usage

# Forward proxy: Listen on IPv6 port 4023 and forward to 127.0.0.1:4022
./port_forwarder --local [::1]:4023 --remote 127.0.0.1:4022 --mode forward

# Reverse proxy: Listen on 127.0.0.1:4022 and forward to IPv6 port 4023
./port_forwarder --local [::1]:4023 --remote 127.0.0.1:4022 --mode reverse

Examples

1. Forward all traffic from IPv6 port 4023 to localhost port 4022:

   ./port_forwarder -l [::1]:4023 -r 127.0.0.1:4022 -m forward
   

2. Reverse forwarding - accept connections on localhost port 4022 and forward to IPv6 port 4023:

   ./port_forwarder -l [::1]:4023 -r 127.0.0.1:4022 -m reverse
   

Building

cargo build --release

The executable will be located at target/release/port_forwarder.

Dependencies
