After compromising an internal Linux host that can reach a restricted VLAN, a penetration tester wants to route all TCP traffic from the tester's Kali workstation through that host over SSH-without defining individual port forwards or forcing every client application to use a SOCKS proxy. Which tool best satisfies this requirement with minimal additional configuration?
Starting an OpenSSH dynamic SOCKS proxy with the -D option and configuring each program to use it
Building individual TCP relays with socat over separate SSH sessions for each destination port
Using the sshuttle utility to create a transparent SSH-based VPN through the compromised host
Launching netcat reverse tunnels on the pivot, one for every required service port
sshuttle installs local firewall rules and multiplexes connections through a single SSH session, so any outbound TCP (and optionally DNS) request automatically traverses the pivot host. Dynamic SOCKS forwarding with the OpenSSH -D switch would still need each application to be proxy-aware. Solutions based on netcat or socat require launching a separate tunnel for each destination port, increasing manual setup.
