This optional configuration allows you to set the IP address for your active network card on your receiving/listening port.
    
        
            
                
                    |  | The OS is responsible for automatically determining the receiving/listening port for your active network card.  Use this optional functionality only if you are noticing issues with receiving multicast traffic from Responder on a given Server machine.  This is otherwise (and in most cases) going to be unnecessary. | 
            
        
     
 
    - Browse to and open any of the Responder service config files (such as Miner.Responder.WindowsServer.exe.config or Miner.Responder.DataServices.exe.config) at this location: C:\Program Files (x86)\Miner and Miner\Responder\Server\. You can edit the files by opening them in an XML application (such as XML Spy) or by opening them in a simple text editing program (such as Notepad).
- Insert the following code in the <appSettings> section, if not already added:
        
            
                
                    
                        |  | 
                                Copy Code
                             |  
                        | 
<add key="MulticastLocalInterface" value="000.000.000.00" />
 |  
 
 
- Set the value to the IP that matches the active network card.
- Save and close the config file. Restart services.
