You'll want to get a google api key if you didn't already. https://console.developers.google.com
Then look in \pogom\utils.py with a text editor and change the host and port to what you want, using 0.0.0.0 is fine, 127.0.0.1 is only useable on localmachine. Then foward the port in your router back to your local pc.
Code:
parser.add_argument('-H', '--host', help='Set web server listening host',
default='127.0.0.1')
parser.add_argument('-P', '--port', type=int,
help='Set web server listening port', default=5000)
