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

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.

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.

Automate network configurations, discover services, and enable secure connectivity across any cloud or runtime. Quickly deploy Consul on Kubernetes leveraging Helm. Automatically inject sidecars for Kubernetes resources. Federate multiple clusters into a single service mesh. Deploy service mesh within any runtime or infrastructure - Bare Metal, Virtual Machines, and Kubernetes clusters, across any cloud. Resolve discovered services through integrated DNS. Automate 3rd party load balancers (F5, NGINX, HAProxy). Eliminate manual configuration of network devices. Secure services running in any environment leveraging intention based policies and automatic mTLS encryption between service mesh resources. Consul enables detecting the deployment of new services, changes to existing ones, and provides real time agent health to reduce downtime. Consul offers support for and integrations with many popular DevOps and Networking tools.

IPv6 CARE, "IPv6 Compliant Automatic Runtime Environment", provides an environment where applications instantly become IPv6-compliant ('patch' mode, see RFC6535). It can also generate a diagnosis about the IPv6 compliance of an application ('check' mode). It uses an LD_PRELOAD-based library injection technique.
