Project V is a set of tools to help you build your own privacy network over internet. The core of Project V, named V2Ray, is responsible for network protocols and communications. It can work alone, as well as combine with other tools.

VTun is the easiest way to create Virtual Tunnels over TCP/IP networks with traffic shaping, compression, and encryption. It supports IP, Ethernet, PPP and other tunnel types. VTun is easily and highly configurable. VPN, Mobile IP, Shaping, etc

An open-source free cross-platform multi-protocol VPN program, as an academic project from University of Tsukuba, under the Apache License 2.0. The API Suite allows you to easily develop your original SoftEther VPN Server management application to control the VPN Server (e.g. creating users, adding Virtual Hubs, disconnecting a specified VPN sessions) from JavaScript, TypeScript, C# or other languages. SoftEther VPN ("SoftEther" means "Software Ethernet") is one of the world's most powerful and easy-to-use multi-protocol VPN software. It runs on Windows, Linux, Mac, FreeBSD and Solaris. SoftEther VPN is an optimum alternative to OpenVPN and Microsoft's VPN servers. SoftEther VPN has a clone-function of OpenVPN Server. You can integrate from OpenVPN to SoftEther VPN smoothly. SoftEther VPN is faster than OpenVPN. SoftEther VPN also supports Microsoft SSTP VPN for Windows Vista / 7 / 8. No more need to pay expensive charges for Windows Server license for Remote-Access VPN function.

Poptop is an open source implementation of a PPTP server. Running under x86 or embedded Motorola ColdFire architectures Poptop provides full interoperability with the Microsoft PPTP VPN client.

Introducing Algo, a self-hosted personal VPN server designed for ease of deployment and security. Algo automatically deploys an on-demand VPN service in the cloud that is not shared with other users, relies on only modern protocols and ciphers, and includes only the minimal software you need. And it’s free. For anyone who is privacy conscious, travels for work frequently, or can’t afford a dedicated IT department, this one’s for you. Really, the paid-for services are just commercial honeypots. If an attacker can compromise a VPN provider, they can monitor a whole lot of sensitive data. Paid-for VPNs tend to be insecure: they share keys, their weak cryptography gives a false sense of security, and they require you to trust their operators. Even if you’re not doing anything wrong, you could be sharing the same endpoint with someone who is. In that case, your network traffic will be analyzed when law enforcement makes that seizure.

A client implementation of Secure Socket Tunneling Protocol (SSTP) for Linux / Mac OS-X that allows remote access via SSTP VPN to Microsoft Windows 2008 Server. This project has been moved to https://gitlab.com/eivnaes/sstp-client

Endian Firewall Community (EFW) is a "turn-key" linux security distribution that makes your system a full featured security appliance with Unified Threat Management (UTM) functionalities. The software has been designed for the best usability: very easy to install, use and manage and still greatly flexible. The feature suite includes stateful packet inspection firewall, application-level proxies for various protocols (HTTP, FTP, POP3, SMTP) with antivirus support, virus and spam-filtering for email traffic (POP and SMTP), content filtering of Web traffic and a "hassle free" VPN solution (based on both OpenVPN and IPsec).

SVPN provides an encrypted tunnel between two hosts, which in combination with IP forwarding enabled on one of the hosts can create a VPN.

Easily share a VPN connection with your virtual machines or containers with this script. Works with IPsec VPN connections (like strongSwan), and lets your VMs reuse the VPN connection of your host system. Create a desktop launcher to start the VPN connection sharing script whenever you need it.

This tool check every x seconds your public ip adress, if it changes (vpn fall down for example) it stops one or several programs. When the VPN crash this tool can send a mail, play a sound. - This tool work on Windows and Linux. - You need to install JAVA 1,8 on your operating system - Download checkvpn.zip and unzip it - Double click on checkvpn.jar - Click on the button « Update ip » when the VPN is stopped to get your public ip address. - Type the programs separated by semicolon that you would like to stop when the vpn is falling down (ex: utorrent.exe;firefox.exe on linux just put « firefox » no extension) - Click on start button and the program will check every x seconds your ip address, if it not the vpn's ip the programs will be stopped by this tool. - The option « auto start » start the process automaticaly. - The ip adress is geolocalized via MaxMind the web site http://check.vpn.free.fr

OpenWRT firmware OpenVPN client for TP-Link routers with small flash, wr740/741/841 based routers with load balancer and custom configuration scripts for fast configuration Open VPN clients. Wireless network does not work, the wireless hardware driver is removed due to a memory shortage (spi flash 4M).

Campagnol is a decentralized VPN over UDP tunneling. It uses UDP hole punching to open connections through NAT/firewall and OpenSSL's DTLSv1 implementation for mutual authentication and encryption.

A Layer 2 Tunneling Protocol VPN client/daemon for Linux and other POSIX-based OSs.

This project allows you to implement your private VPN by route IP package through a special plugin you choice.

TP-Link WR740/741 version 4.xx, upgraded with 16MB (original is 4MB) spi flash and make and install OpenWRT version 22.03.3 and other software (Squid proxy, htop, Midnight commander, Dual WAN support, Load balancer, AdGuard, Wireless Shedule, OpenVPN Client and others.

vtrunkd - network link bonding and multichannel VPN. Vtrunkd is a Linux VPN daemon used to combine several connection paths into one aggregated channel. Features latency, reordering and jitter management, behaviour analysis optimizations for encapsulated protocols, bufferbloat control, packet redundancy, and multiple cpu cores utilization. Up to 30 heterogenous links bonding supported. Used for live streaming, LTE/3G/Wi-Fi link bonding. 32/64-bit, x86, MIPS and ARM supported. Supports python plug-ins for new algorithms implementation. Open source version developed and commercial support provided by Vrayo Systems, http://vrayo.com. No encryption supported yet.

CARMA VPN is a network management program written in PERL and CGI to assist in the implementation and management of a large fully meshed, fault tollerant, VPN network. The base network platform that CARMA VPN was developed for is Cisco IOS.

This contains a sample implementation of DTLS-VPN using OpenSSL DTLSv1 Support - to send data over an encrypted channel.

Gnome2 GUI for the Cisco vpnclient.

This project focuses on bringing commercial quality L2TP support to Linux and possibly other Unixes. L2TP stands for Layer 2 Tunneling Protocol. It is a VPN similar to PPTP and a number of others. L2TP often competes with PPPoE.

Lomalarga is a port forwarding (VPN-like) service based on SSH & Linux. Based entirely on open source. The client is written in C# and the administration is based on Linux/lighttpd/PostgreSQL/PHP, with the UI written with Google Web Toolkit.

M0n0wall currently doesn't support IPSEC VPN where one or both ends are dynamic IP addresses. This PHP script along with the dynamic DNS service built into m0n0wall, auto-updates the remote gateway IP address in the VPN configuration.

Muti-link VPN aims to bound muti-link communication channel(wired or wireless) to be a single VPN channel between two linux box.
