SOLVED - port forward to daemon listing on loopback address

[kent_dorfman766]

I'm posting this here becasue the solution is something someone else may find useful.

My e-lab is in my basement and my dev workstation is in my main-floor office. The e-lab has a Debian server that hosts USB connected microcontroller dev boards. STmicro provides a TCP/USB bridge application called stlink-server. Unfortunately the thing is hardwired to only listen on the loopback address so anything connecting to it must be running on the local host.

I remember there being a netcat swiff-army-knife type application that could bridge and forward ip traffic between different ip/port cominations, but it's been years and I don't remember the application name or the configuration. NOTE! this is user-space forwarding. I'm not interested in any of the iptables/netdev stuff that does forwarding from kernel space.

Does anybody understand what I'm getting at and remember the name of the application I'm thinking of?
