NATMap
TCP/UDP port mapping for full cone NAT
This project is used to establish a TCP/UDP port mapping from an ISP NAT public address to a local private address. If all layers of NAT are full cones (NAT-1), any host can access internal services through the mapped public address. In bind mode, all traffic does not go through this program. -

PJSIP
PJSIP project
PJSIP is a free and open-source multimedia communication library written in C language implementing standard-based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. It combines signaling protocol (SIP) with a rich multimedia framework and NAT traversal functionality into high-level API that is portable and suitable for almost any type of system ranging from desktops, and embedded systems, to mobile handsets. PJSIP is both compact and feature rich. It supports audio, video, presence, and instant messaging, and has extensive documentation. PJSIP is very portable. On mobile devices, it abstracts system-dependent features and in many cases is able to utilize the native multimedia capabilities of the device. -

Urbit
An operating function
...Urbit is for everyone, but sometimes it is easy to get lost in this universe. It solves the hard problems of implementing a peer-to-peer network (including identity, NAT traversal, and exactly-once delivery) in the kernel so app developers can focus on business logic. The entire OS is a single pure function that provides application developers with strong guarantees: automated persistence and memory management, repeatable builds, and support for hot code reloading. Urbit is a personal OS designed from scratch to run peer-to-peer applications. ... -

UFTP
Encrypted UDP based FTP with multicast
...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. -

backconn
allows connecting to hosts behind firewalls and NAT
backconn is a networking tool that is supposed to solve the problem of connecting to devices that are behind a firewall or a NAT box. It is a set of two programs: backconn-cli and backconn-adm. backconn-cli needs to be installed on the device you wish to have access to, while backconn-adm is the server part, and needs to be installed on a publicly available host. -

Those who have read past the "Malware" warning can be assured there is absolutely no malware in this OS or in the download. This warning comes from the "netcat" binary included in the download as a DOS time client. Unfortunately netcat has code that is flagged as malware. FREESCO, a NAT/firewall router/server based on Linux and runs on a single 1.44MB floppy. Freesco is very powerful and versatile and can connect multiple home or small office networks to most types of Internet connections including dialup.

NatTraversal
Build NAT to NAT tunnel with a third-party php server.
NatTraversal: Build NAT to NAT tunnel with a third-party php server. NatTraversal also need an stun server to obtain the mapped (public) IP address (NAT address) and port number that the NAT has allocated for the application's User Datagram Protocol (UDP) connections to remote hosts. Usage: copy www/* to your php server, and chmod all *.txt file, make sure we can read and write to this files through php. -
