Trying to set Fiddler as a Reverse Proxy

I have been trying to set Fiddler as a Reverse Proxy, I've been following these instructions, but I just don't understand the point 3.

Option #1: Configure Fiddler as a Reverse-Proxy Fiddler can be configured so that any traffic sent to http://127.0.0.1:8888 is automatically sent to a different port on the same machine. To set this configuration:

  1. Start REGEDIT
  2. Create a new DWORD named ReverseProxyForPort inside HKCU\SOFTWARE\Microsoft\Fiddler2.
  3. Set the DWORD to the local port you'd like to re-route inbound traffic to (generally port 80 for a standard HTTP server)
  4. Restart Fiddler
  5. Navigate your browser to http://127.0.0.1:8888

How can I set the DWORD to the local port??? Sorry Im novice in network connections, please hope some good fellaw could explain step by step how can I do that. Do I have to do it inside Fiddler? Do I have to do it in windows? Im using windows8.1

PD: I know Im missing that step, cuz after doing steps 4 and 5 I get this message in the browser: "[Fiddler] The connection to '127.0.0.1' failed. Error: ConnectionRefused (0x274d). System.Net.Sockets.SocketException No connection could be made because the target machine actively refused it 127.0.0.1:8888"

EDIT>

When I set on fiddler>Fiddler Options>Connections>Fiddler listens on port: 8888 I get the same message, but instead of 127.0.0.1:8888 now I get 127.0.0.1:80

[Fiddler] The connection to 'localhost' failed. Error: ConnectionRefused (0x274d). System.Net.Sockets.SocketException No connection could be made because the target machine actively refused it 127.0.0.1:80

I have notice that in fiddler set reverse proxy page, it says... Configure Fiddler as Reverse Proxy: To use this method, the hostname for the request to reroute must be 127.0.0.1:8888, localhost:8888, [::1]:8888, or the machine's NETBIOS hostname on port 8888.

Is perhaps that why I can't get it to work? how can I set my machine NETBIOS hostname on port 8888?

I had the same issue... this fixed it...

  1. In the menu click 'Tools' >> 'Fiddler options' >> 'Connections'
  2. Find out the port number

Use the port number noted here instead! e.g. http://127.0.0.1:[port number]

Let's step back a bit. Why specifically are you trying to run Fiddler as a Reverse Proxy? What service are you trying to pass traffic into (e.g. IIS?) What port did you move that service to? What is the exact (original) URL of the traffic you're trying to collect?

You don't need to mess with the registry if you're going to write FiddlerScript.
