Open Source BSD Tunneling Software

UFTP is an encrypted multicast file transfer program, designed to securely, reliably, and efficiently transfer files to multiple receivers simultaneously. This is useful for distributing large files to a large number of receivers, and is especially useful for data distribution over a satellite link (with two way communication), where the inherent delay makes any TCP based communication highly inefficient. The multicast encryption scheme is based on TLS with extensions to allow multiple receivers to share a common key. UFTP also has the capability to communicate over disjoint networks separated by one or more firewalls (NAT traversal) and without full end-to-end multicast capability (multicast tunneling) through the use of a UFTP proxy server. These proxies also provide scalability by aggregating responses from a group of receivers.

Cntlm is an NTLM / NTLMv2 authenticating HTTP/1.1 proxy. It caches auth'd connections for reuse, offers TCP/IP tunneling (port forwarding) thru parent proxy and much much more. It's in C, very fast and resource-efficient. Go to http://cntlm.sf.net/

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

Nipe is a Perl-based engine whose primary aim is to make the Tor network act as the default gateway for outgoing traffic. In practice, it configures system firewall rules (iptables) and network routing so that almost all IPv4 traffic is redirected through Tor. The tool provides commands such as install, start, stop, restart, and status to manage its behavior. When “start” is issued, it sets up the necessary rules; when “stop” is used, it attempts to remove those rules. Nipe currently operates over IPv4 and does not yet support IPv6, meaning that users with IPv6 connectivity may bypass Tor routing. It includes a Dockerfile to facilitate containerized usage, requiring sufficient network capabilities (e.g. NET_ADMIN) inside the container. Behind the scenes, the code is modular: for instance, parts of the logic around installation and utility functions are separated into Perl modules (e.g. in lib/Nipe/Utils/Install.pm).

Enables tunneling of network connections through restrictive HTTP proxies. Features: Portmapping, SOCKS4, SOCKS5, web-based admin interface, possibility to use standalone server (perl) or hosted server (PHP), optional authorization from LDAP or MySQL

Convert Webmail to POP3.Is also included a SMTP/POP3 tunneling system that allow send and receive email in a private network HTTP PROXY based. All connection are plugin based. Over 450 email server supported and tested, GMAIL POP3/SMTP over Proxy Network.

Bypass is an IP forwarding/tunneling tool which can be used where limited bypassing of a firewall is necessary, but relaxing the restrictions in the actual firewall is not an option. The aim is for bypass to be automatic and transparent.

TCP over RDP tunneling tool

IPtools is an all in one package that includes various TCP/IP tools. Server: - FTP - TFTP - Syslog - Web - Remote Command - General UDP server - Multicast server Client utilities: - Multicast client - TFTP client Starting on version 0.2.0, a powerful network connection tools UBridge is added, it can bridge: - VXLAN (newly released) - UDP sessions - NIC card of the PC - Connections to Cisco Router Simulator "GNS3/dynamips" and H3C Router Simulator (LITO/CEN). UBridge can also be used as a Ethernet over UDP tunnel to remote bridge PC's local NIC, VXLAN, UDP proxy etc. Visit the Wiki page for detail. GUI tools include a network monitoring tool PMON, a SNMP and IP scanner. The project aim is to make them as light weight tools that can be directly executed in command prompt without the need of installation. (Except pmon and UBridge to bridge PC's NIC which require Winpcap). The whole package can be put into USB flash and 伴侶highly portable.

WAR3Proxy is a Warcraft 3 (ROC+TFT) Proxy Server. Currently it allows your Warcraft 3 client to connect to a B.NET server or pvpgn, and it will proxy both the chat and game connections. It will be extended into tunneling these connections.

JavaTunnel is a java, free, tunneling program. It can function in two ways: 1 It can open TCP/IP tunnel between two computers, using HTTP as a transport(not yet). 2 It can open a connection directly, witht he help of a SSL-HTTP proxy(avaible now).

phc -- proxy hunter customed -- for validation of free SOCKS 4/5 or HTTP proxies. It is highly customed. Current first release 1.0 validate http proxies from a file with CONNECT or GET method bypass a basic auth http tunnel. Delay is recorded, too.

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.

VJDBC (Virtual JDBC) is a JDBC type 3 driver which provides efficient tunneling of JDBC commands/results over different communication protocols (RMI, HTTP, HTTPS ...).

Command line and wxWidgets UI for an HTTP(S) proxy that can tunnel web requests over one or more SSH tunnels to one or more web specified servers, while using a direct connection for all other traffic.

Aleksoft Proxy allows tunneling TCP/IP traffic through a proxy server located outside of both service provider and consumer firewalls. The proxy consists of two executables, listener and connector, which may run on the same or different computers.

Tunnel all your your shell commands/tools through HTTP, Socks4 or Socks5 proxies. Different proxy types can be mixed in the same chain and supports authentication for HTTP and Socks5. It works by hooking all the calls to connect().

This project intends to make a SOCKS compatible tunnel proxy which communicates to the server part, running on your nameserver, over standard DNS (UDP) protocol. That way you can bypass network firewalls allowing no other IP traffic but DNS.

Enable servers behind a firewall to export services to the external networks with the assistance from an externel host as proxy (Jumppoint). The firewall tunnel consists of two parts: a frontend as "Jumppoint" and a backend running behind the firewall

HTTP Proxy Client is the set of libraries and scripts, provides transparent access to Internet via HTTP proxy tunnel for programms, which uses TCP/IP for communication. The tunnel provided by CONNECT method of HTTP proxy. Supported external DNS resolving.

tunnel a tcp/udp connection through a http(s) connection, surviving proxy-servers

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.

An easy, yet highly-configurable iptables-based firewall solution designed for everybody from home users to network admins. Functionality for IPv6, tunneling, IPSec, and advanced routing is planned.

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.
