Pingtunnel

Pingtunnel is a Go-based tunneling tool that sends TCP and UDP traffic over ICMP. It is designed for experimental, research, and network-study scenarios where ICMP transport is being explored as an alternative path for traffic forwarding. The project uses a client and server model, with the server typically requiring a publicly reachable host. It can carry application traffic through ICMP echo-style communication, which makes it distinct from common TCP, UDP, HTTP, or DNS tunnel tools. Because the tunnel traffic is not inherently presented as encrypted, sensitive usage should rely on secure protocols layered above it. pingtunnel is best understood as a specialized transport experiment for moving traffic through ICMP rather than a full privacy or security solution.
