Using SSH local forwarding tunnel
We will use Putty (http://www.putty.org/) to show how you can set up a SSH tunnel.
Create a new session in PuTTY
Assuming your your SSH server has an IP address 126.96.36.199, and your NETCONF server has a private address 192.168.10.103 and it can only be accessed through the host 188.8.131.52.
and then select the "Tunnels" tab in the "SSH" section
In the Source port text box enter 830. This is the port PuTTY will listen on on your local machine. It can be any standard Windows-permitted port.
In the Destination field immediately below Source port enter 192.168.10.103:830. This setting instruct your SSH server to forward the connection
to an private IP 192.168.10.103 port 830.
Click the "Add" button and the screen should look like this,
Save your tunnel configuration by returning to the "Session" tab and click "Save"
Now click "Open" to establish your SSH tunneling tunnel.
Then start NETCONFc, select "Connect | Over SSH", in the "Host" field, enter "127.0.0.1", and also enter values for other fields
such as "User name" and "Password" , and then you should be able to connect to your remote server.
