Pingtunnel is a tool that send TCP/UDP traffic over ICMP

This project is a high-performance reverse proxy designed to expose local services to the internet. It provides a comprehensive suite of tools for managing network traffic, including support for TCP and UDP stream multiplexing, connection pooling, and load balancing across proxy instances. The system facilitates secure communication through TLS encryption, data compression, and multiple authentication methods such as OpenID Connect, shared tokens, and basic password protection. The software offers granular control over HTTP traffic, enabling users to route requests based on subdomains or URL

Bypass firewall for traffic forwarding using webshell

dnscat2 is a DNS tunneling tool and covert command and control server that encapsulates encrypted traffic within DNS queries and responses. It functions as an encrypted DNS proxy designed to bypass network firewalls and establish communication paths when standard outbound ports are blocked. The project enables the creation of covert network channels by acting as an authoritative nameserver. It supports remote command execution through interactive shells and provides a mechanism for tunneling TCP network traffic to reach restricted remote hosts. The system includes capabilities for multiplexe

ngrok is a secure TCP tunneling proxy and API ingress controller that exposes local services to the public internet. It establishes a persistent connection between a local agent and a cloud-based gateway to route traffic to local ports without requiring firewall or router configuration changes. The project provides a global gateway for routing API traffic, which includes built-in support for rate limiting and authentication policy enforcement. It also functions as an IoT device gateway, enabling remote command execution and access control for embedded hardware via a cloud-to-device bridge. A

Neo-reGeorg is a project that seeks to aggressively refactor reGeorg

This project is a multi-protocol proxy server and network tunneling tool designed to manage traffic across heterogeneous infrastructure. It functions as a traffic management gateway, providing the core infrastructure to route, filter, and secure network connections through a unified interface. The software distinguishes itself through its support for cascading proxy chaining and dynamic upstream load balancing, which allow for the creation of complex, multi-hop network paths. It provides granular control over traffic flow by normalizing diverse protocols, enabling transparent port forwarding,
