MITMf come proxy trasparente?

È possibile utilizzare MITMf per sniffare come proxy trasparente? Se mi collego a questo proxy vorrei vedere il mio vero IP, non l'IP del server. Se possibile, come posso farlo? Ho trovato questo file "ClientRequest.py", ma non conosco Python. Forse qualcuno può aiutarmi a impostare il proxy per non modificare le intestazioni?

class ClientRequest(Request):

    ''' This class represents incoming client requests and is essentially where
    the magic begins.  Here we remove the client headers we dont like, and then
    respond with either favicon spoofing, session denial, or proxy through HTTP
    or SSL to the server.
