Reverse Tunnel
A technique in which an internal network host actively initiates a connection to an external server to establish a remote access channel that bypasses firewall and NAT restrictions. It is often used by malware to establish C2 channels.

Reverse tunnels exploit the fact that internal-network machines allow outbound connections, and are often used by malicious code to bypass perimeter defenses.
OpenTandem's connection mechanism is essentially a reverse tunnel solution, where a lightweight agent running on the computer actively initiates a persistent connection to a relay server, requiring no open ports on the router or public IP configuration
Unlike SSH direct connection, which requires the computer to have a reachable public network address, reverse tunneling only requires the computer to have outbound internet access
