🌐 go-dualstack-ipv6-proxy

go-dualstack-ipv6-proxy is a high-performance HTTP/HTTPS proxy server written in Go, designed to handle incoming IPv4 and IPv6 requests and forward them through randomized IPv6 addresses from a user-defined pool. This makes it especially useful for applications that benefit from IP rotation over IPv6 networks.

---

🚀 Features

• 🔁 Dual-stack support: Accepts both IPv4 and IPv6 connections
• 🧠 IPv6 randomization: Routes traffic through randomly chosen IPv6 addresses from defined subnets
• 🔐 HTTPS support: Easily enable TLS with your own certs
• 🛡️ IP filtering: Simple allowlist-based access control
• ⚙️ Highly configurable: All major settings controlled via config.toml
• 📈 High throughput: Supports thousands of concurrent connections

🛠️ Configuration

Create a configuration file in TOML format (e.g., config.toml) as shown below:

[server]
listen_port = "8080"                # HTTP port
listen_port_https = "9999"          # HTTPS port
max_connections = 10000             # Maximum number of simultaneous connections
idle_timeout_seconds = 90           # Idle connection timeout
read_timeout_seconds = 30           # Read timeout for each connection

[ssl]
enabled = true                      # Enable HTTPS
cert_path = "/root/ipv6-proxy/cert/cert.pem"
key_path = "/root/ipv6-proxy/cert/key.pem"

[authorization]
allowed_ips = [
    "*"                             # Allow all incoming IPs (use specific IPs or CIDRs to restrict)
]

[ipv6_pools]
subnets = [
    "2a14:7584:44b3:0::/118"        # IPv6 subnet to use for outgoing connections
]
addresses_per_subnet = 1000        # Number of random addresses to generate per subnet

exclude = [
    "::1"                           # IPv6 addresses to exclude from the pool
]
