Tunnelling UDP Traffic Through An SSH Connection

Overview

This section describes how to use NST to tunnel a UDP traffic conversation through a SSH connection. For our example we will tunnel IPMItool traffic (UDP Port: 623) through an SSH connection to a Sun Fire X4200 server. Three systems are involved, 2 NST probes and the x4200 server. Reference information was taken from: "Performing UDP tunneling through an SSH connection".

Tunnel A TCP Forward Port Through SSH

First we need to tunnel a non-used TCP port from the local NST probe to the remote NST probe which shares the same LAN as the destination x4200 server.
