A basic VPN tunnel implementation written in Rust.

Simple VPN is a rudimentary implementation of a VPN tunnel, allowing users to establish a virtual private connection. Built in Rust, it showcases the robustness and efficiency of the language while providing basic tunneling capabilities.

• VPN Server and Client Modes.
• AES-256-GCM encryption for data security.
• TUN interface configuration for both server and client.
• Simple command-line interface using clap.
• Logging with different verbosity levels.

• Rust and Cargo: Ensure you have the latest versions installed. If not, visit Rust's official page for installation details.
