I'm trying to run a Python2.7/Cherrypy web server on Win 7 which is connected to a VPN to establish a dedicate IP address. (If I run the exact same application on Win XP connected to the VPN it works fine.) On Win 7 I tried configuring it to use port 8080, 8005, or 80 with no improvements. I turned off Windows Firewall altogether to test and there was no improvement. If I run Apache on the Win 7 machine on port 80 it works fine so I'm pretty sure it's not the VPN service or router.

If I go to WhatismyIP.com it shows that I have the IP address being provided by the VPN.

Here is the Python code, but I suspect the problem is the network configuration:

import cherrypy

class HelloWorld:
    def index(self):
        return "Hello world!3"
    index.exposed = True

cherrypy.root = HelloWorld()

cherrypy.config.update({"global":{  "server.environment": "production",
                                    "server.socketPort": 8005    
                                    } 
                            })

cherrypy.server.start()

This will return a web page if I go to localhost:8005, but not if I go to the VPN IP address:8005 from another machine. As I said, if I run Apache on the Win 7 machine on port 80 I can see it at localhost:80 AND at the VPN IP address:80 from another machine.

Thanks for any light you can shed!
