Nice info! I was just in the middle of getting a Xbox online
Question is (most of all for the dev team) the port number 88 is used for Kerberos, and Zentyal 3.0 will probably include Kerberos.
Will we get into trouble if port 88 is forwarded to the Xbox device?
Another question, port 80 is for the web server. If we add the postservice hook, will we run into problems with the webserver running on the Zentyal box?
