frp
A Fast Reverse Proxy
frp stands for exactly what it is: a fast reverse proxy. It helps you expose a local server behind a NAT or firewall to the Internet. It is currently under development, but already supports TCP and UDP, as well as HTTP and HTTPS protocols where requests can be forwarded to internal services by domain name. It also has a P2P connect mode and many other nifty features. These include configuration files, environment variables, a dashboard that shows you frp's status and proxies' statistics information, an Admin UI that helps you check and manage frpc's configuration, and many others. -

go-libp2p
libp2p implementation in Go
go-libp2p is the official Go implementation of the libp2p networking stack, a modular and extensible framework for peer-to-peer communication. Used in systems like IPFS and Filecoin, go-libp2p abstracts away the complexity of building decentralized networks by handling discovery, transport, security, and multiplexing layers. Its modular architecture allows developers to customize network behavior while maintaining interoperability with other libp2p implementations. It empowers developers to... -

FireHOL
A firewall for humans.
FireHOL is a language (and a program to run it) that builds secure, stateful firewalls from easy-to-understand, human-readable configurations. The configurations stay readable even for very complex setups. FireQOS is a program that sets up traffic shaping from an easy-to-understand and flexible configuration file. Both programs abstract away the differences between IPv4 and IPv6. so you can concentrate on the rules you want. You can apply rules for IPv4 or IPv6, or both, as you need. -

ttl
Fast, modern traceroute with real-time TUI, per-hop stats
ttl is a modern traceroute-style network diagnostic tool built to feel more like an interactive, real-time “mtr replacement” than a one-shot traceroute dump. It uses a full-screen terminal UI to continuously probe paths and refresh hop-by-hop measurements, which makes transient loss, jitter, and routing changes much easier to spot. The design emphasizes per-hop visibility with live statistics, and it enriches what you see by resolving network identity details like ASN and geolocation when... -

Kilo
Kilo is a multi-cloud network overlay built on WireGuard
...Kilo connects nodes in a cluster by providing an encrypted layer 3 network that can span across data centers and public clouds. The Pod network created by Kilo is always fully connected, even when the nodes are in different networks or behind NAT. By allowing pools of nodes in different locations to communicate securely, Kilo enables the operation of multi-cloud clusters. Kilo's design allows clients to VPN to a cluster in order to securely access services running on the cluster. -

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. -

Udp2raw-tunnel
Turns UDP traffic into encrypted UDP/fakeTCP/ICMP traffic
...Linux host (including desktop Linux,Android phone/tablet,OpenWRT router,or Raspberry PI) with root account or cap_net_raw capability. ICMP/FakeTCP headers help you bypass UDP blocking, UDP QOS or improper UDP NAT behavior on some ISPs. In ICMP header mode,udp2raw works like an ICMP tunnel. UDP headers are also supported. In UDP header mode, it behaves just like a normal UDP tunnel, and you can just make use of the other features (such as encryption, anti-replay, or connection stalization). -

Legacy Game Netplay System
Automatic game launcher for emulators (PS2 edition)
...The current edition can connect any two players on the planet using LogMeIn VPN, but also supports direct peer to peer connection over internet if at least one of the players has NAT traversable internet connection. You must read the 'readme.txt' carefully as there will be some setup to be done before you can play - both players should follow identical setup with exception that one should start the game with player1.bat and other with player2.bat. Current version supports Playstation 2 emulator but the system supports numerous other emulators, support for which along with graphical interface for setup might be added in future. -

FlippingBitbot
Vulnerable VM featuring Bitbot
...This is the second of many to come, please feel free to supply feedback so I can make future ones more enjoyable and fulfilling. The network configuration of the VM is set to auto, so it is easiest to run with some sort of DHCP server on the same network(or just select the NAT option in your virtualization software). It is suggested that you use the NAT option along with port forwarding, but as long as you have TCP access to the VM, you should be fine. There are no supplied credentials, and it is intended that the network services on the VM are the attack vectors. If you have questions, feel free to ask in #vulnhub on freenode(I'm bwall on there). ... -
