Socat

Prerequisites

• socat installed on the host where you are forwarding traffic.
• Appropriate firewall rules allowing listening ports.

Forward From Local Listen Port to Attack Host

socat TCP4-LISTEN:8080,fork TCP4:<IPaddressofAttackHost>:80

• Listens on local port 8080.
• For each connection (fork), connects to <IPaddressofAttackHost>:80.

Forward From Local Listen Port to Target Host

socat TCP4-LISTEN:8080,fork TCP4:<IPaddressofTarget>:8443

• Listens on 8080.
• Forwards to <IPaddressofTarget>:8443.

Great for simple TCP relays when you can’t run more complex tunneling tools.
