Port-Forwarding a server started using native python socket library

[abhigenie92]

Hi, guys! I have been trying to find such a tool since a long time. But I am a bit confused from the docs, please have a look below.

I start a server using the native library:

def register_audio_port(self):
        '''register audio socket and start thread for receiving connections'''
        self.sock_audio = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.sock_audio.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        self.sock_audio.bind(('0.0.0.0',0)) # 0.0.0.0 will allow all connections
        audio_port=self.sock_audio.getsockname()[1]
        self.sock_audio.listen(75)

How can I port-forward using your library on a already started server?
