Python p2p chat client/server with built-in NAT traversal (UDP hole punching). I've written an article about the detailed implementation (in Chinese). The number 100 is used to match clients, you can choose any number you like but only clients with the same number will be linked by server. If two clients get linked, two people can chat by typing in terminal, and once you hit <ENTER> your partner will see your message in his terminal. Encoding is a known issue since I didn't pay much effort on making this tool perfect, but as long as you type English it will be fine.
This project implements a simple STUN server and client on Windows, Linux, and Solaris. The STUN protocol (Simple Traversal of UDP through NATs) is described in the IETF RFC 3489, available at http://www.ietf.org/rfc/rfc3489.txt
The Interactive Connectivity Establishment (ICE) protocol combines various NAT traversal utilities such as the STUN and TURN protocols in order to offer a powerful mechanism that allows Offer/Answer based protocols such as SIP and XMPP to traverse NATs. This project provides a Java implementation of the ICE protocol that would be usable by both SIP and XMPP applications. The project also provides features such as socket sharing and support for Pseudo TCP.
frp is a fast reverse proxy to help you expose a local server behind a NAT or firewall to the internet. Now, it supports tcp, udp, http and https protocol when requests can be forwarded by domains to backward web services. Expose any http and https service behind a NAT or firewall to the internet by a server with public IP address(Name-based Virtual Host Support). Expose any tcp or udp service behind a NAT or firewall to the internet by a server with public IP address.
A SIP signalling consolidation tool that allows multi-user management of diverse SIP providers and allows central management of any SIP based VoIP service. Included in this project are a SIP Stack, SIP Registrar, SIP Registration UAC, SIP Stateful Proxy, STUN Server and more. ...
Version 1.2. This is the source code to STUNTMAN - an open source STUN server and client code by john selbie. Compliant with the latest RFCs including 5389, 5769, and 5780. Also includes backwards compatibility for RFC 3489. Compiles on Linux, MacOS, BSD, Solaris, and Win32 with Cygwin. Windows binaries avaialble from www.stunprotocol.org.
A simple signaling server for clients to connect and do signaling for WebRTC. It also supports vending STUN/TURN servers with the shared secret mechanism as described in this draft. This mechanism is implemented e.g. by rfc-5766-turn-server or by a patched version of restund.
Pull Request is welcomed. First, you need to clone the project to your account, and then modify the code on the dev branch. Finally, Pull Request to dev branch of goproxy project, and contribute code for efficiency. PR needs to explain what changes have been made and why you change them. This page is the v6.0 manual, and the other version of the manual can be checked by the following link.
Mr.2 can help you expose local server to external network. Support both TCP/UDP, of course support HTTP. Keep it simple, stupid. See releases for other platforms. Or go get github.com/txthinking/mr2/cli/mr2.
a nodejs module for local and remote Inter Process Communication with full support for Linux, Mac and Windows. It also supports all forms of socket communication from low level unix and windows sockets to UDP and secure TLS and TCP sockets. This work is licenced via the DBAD Public Licence.
Alfandega is a strong and Modular IpTables Firewall. It provides NAT, port-forwarding, spoofing list, blacklist of crackers and spywares sites, protection for tcp/udp scans, DOS/DDOS and Smurf attacks, TCP tuning, DHCP and PPP support and much more.
Documentation can be found at kademlia.readthedocs.org. This library is an asynchronous Python implementation of the Kademlia distributed hash table. It uses the asyncio library in Python 3 to provide asynchronous communication. The nodes communicate using RPC over UDP to communiate, meaning that it is capable of working behind a NAT.
PeerVPN is a software that builds virtual ethernet networks between multiple computers. Such a virtual network can be useful to facilitate direct communication that applications like file sharing or gaming may need. Often, such direct communication is made impossible or very difficult by firewalls or NAT devices.
