About:
Tcptunnel is a lightweight utility that forwards incoming TCP connections from a local port to a specified remote host and port. It acts as a simple proxy, enabling access to services behind firewalls or facilitating network debugging and testing scenarios. The tool is designed for ease of use with minimal configuration.

Key Features:

Lightweight and fast TCP proxy
Simple command-line interface
Supports IPv4 and IPv6
No external dependencies

Use Cases:

Forwarding traffic to services behind NAT or firewalls
Debugging network applications by relaying traffic
Load balancing simple TCP services

Alternatives:

socat – More versatile but with a more complex syntax
netcat – Often pre-installed, but less optimized for persistent forwarding
