Chisel is a handy red-team tool. I learned about it training for the OSCP (Offsec Certified Professional). It comes in handy under certain situations.

Another tool I recommend is Ligolo-ng [1]. You set up a network interface and use "ip route" to send traffic through it. In a way, it "feels like a VPN".
