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's Integrated Lights Out Manager (ILOM) service processor network interface. Three systems are involved, 2 NST probes and the x4200 server. Reference information was taken from: "Performing UDP tunneling through an SSH connection".
Step By Step:
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.

In this example SSH is being NATed through a firewall. The SSH listening port is: "31222". We have choosen to use TCP port forward the "non-used" TCP port: "9999". The remote NST probe's IP address is: "55.44.22.178".
