Open Source C++ Tunneling Software for Linux

Amnezia VPN is an open-source VPN client that enables users to easily deploy and manage their own self-hosted VPN server. Designed for both desktop and mobile platforms, it simplifies VPN setup by automatically installing and configuring VPN services on a user's server through a guided interface. The platform supports multiple VPN protocols, including OpenVPN, WireGuard, IKEv2, and its proprietary AmneziaWG protocol. Amnezia VPN also provides advanced traffic obfuscation technologies to help bypass censorship and improve privacy in restrictive network environments. With split tunneling capabilities and support for Windows, macOS, Linux, Android, and iOS, it offers flexible control over VPN usage across devices. Its combination of self-hosting, protocol diversity, and ease of deployment makes it a powerful solution for secure and private internet access.

NekoBox for PC is a Qt-based, cross-platform proxy configuration manager designed for Windows and Linux systems. It provides a user-friendly graphical interface for managing advanced proxy and tunneling configurations using the sing-box backend. NekoBox supports a wide range of modern proxy protocols, making it suitable for users who need flexible and powerful network routing options. The application offers portable builds that run without installation, allowing quick setup and easy deployment. With support for subscription-based configurations and custom cores, it caters to both casual users and advanced networking enthusiasts. Although the project has been archived and is no longer actively maintained, NekoBox for PC remains a popular and capable tool for managing complex proxy setups.

Ssh terminal, file transfer and tunneling tool. The focus is on running tunnels inside tunnels. That one has to jump through several machines. Please see the wiki pages for documentation. https://sourceforge.net/p/doffensshtunnel/wiki/Home/

UDPspeeder is a tunneling utility focused on improving UDP traffic quality over high-latency, unstable, or packet-loss-prone links. Its core technique is Forward Error Correction, which sends redundant data so the connection can recover from packet loss without waiting for retransmission. Used by itself, it improves UDP-based connections, but it can also be paired with UDP-based VPN tools to support broader traffic types through the VPN layer. The project is especially relevant for gaming, remote access, VPN transport, and other latency-sensitive use cases where packet loss creates visible performance problems. It gives users adjustable parameters so they can balance bandwidth overhead, latency, and resilience. UDPspeeder is not a general VPN by itself, but a network-quality enhancement layer for UDP tunnels.

Kinoglaz is a pure C++ RTSP Streaming Server. Features seek / scale support, TCP tunneling, playlists, runtime stream composition. Actually supports MPEG4 video (like xvid), MPEG2 / MP3 / AAC audio.

HTTP Tunnel that works with ANY HTTP proxy: no CONNECT method required! You can use the port redirector or Socks 4/4a/5 to connect outside your (restricted) LAN. An external web server is required, to be used as gateway.

NitroOnline is a project to bring the Nintendo DS handheld online using advanced optimization techniques, cleaner than tunneling. We intend to develop the project in C, whilist device driver and some kernel extensions are done in C++.

Cross-platform open source database management tool for Redis. RDM is easy-to-use GUI tool available for Windows, Linux, MacOS and iPadOS. Analyse your Redis ® memory usage with RDM and remove obsolete data with bulk removal. RDM supports all latest Redis ® features: ACL, Streams, Cluster, Sentinel, ReJSON module, HyperLogLog, etc. Build-in TLS, SSH and TLS-over-SSH tunneling for easy and secure access to any redis-server. RDM works with Amazon ElastiCache, Microsoft Azure Redis Cache, Digital Ocean and other Redis ® clouds. RDM displays JSON, MessagePack, CBOR, PHP, Pickle, numpy.Array, pandas.DataFrame and binary data in human readable form and supports Native Formatters. RDM offers you an easy-to-use GUI to access your Redis ® databases and perform some basic operations. RDM allows to perform bulk operations which simplifies developer daily routines.

SSHgate is a small daemon that transparently routes packets across SSH encrypted tunnels.

This project provides a program for the capturing, editing and saving data from a SXM scanning tunneling microscope (http://sxm4.uni-muenster.de/stm-en/). The program is developed in C++ and based on a Qt library from TrollTech and libusb library.

The project bahamut is a full ad-hoc tunneling software to be used by the Playstation Portable (PSP) to emulate online features. MOVED TO: https://github.com/codestation/bahamut

Multipurpose http tunnel which runs through any firewall or proxy. It uses CONNECT method but also BOSH-like method which makes run it on any proxy (even http 1.0).

mod_tunnel is a simple Apache 1.3.x module that can be used to create TCP tunnels using your web server. It comes handy to expose services which can be reached through a proxy, bypassing firewalls.

Predefined CORBA architecture to develop software into two parts : the real computer kernel (server) and the exploitation or UI part (client). Sources are independant of the CORBA distribution (MICO, omniORB, ORBacus, TAO, Visibroker) and are fully portable. JAVA Servlets for HTTP tunneling. The Server is in C++ and the Client in C++ and JAVA.Very usefull in real time projects. This is a small sample to be adapted to your project.

sshh allows you to make a persistent tcp connection (tunnel) over an http proxy. Once you have it set up, you can make new connections from either end. Similar in concept to httptunnel but more versatile and scalable.

xmelee is an xbox peer-to-peer tunneling program. It enables lan games (system link) to be played over the internet. The packetization is highly optimized which permits the lowest lag possible when extending game play over the internet.
