Why on earth they don't understand that 1 outbound port is all that is required for their traffic I'll never know.

Thanks

It's still typical of the game industry. "Just open these multitude of ports and you'll be fine." The assumption seems 
to be the evil network administrators are trying to block your game play, so we'll not give specific information. The 
specifics would permit me to block their servers, yes, but also allow me to work around issues of firewalls or 
bandwidth management devices in a sane manner.

In the past, I would sometimes craft a specific permit class on our old Packetshaper to permit just the ports 
referenced and what I could find of the game servers, to avoid opening random ports or classifying them for a high 
quality of service based on port alone. I do hear Bungie is attempting to work with Procera, among others, to properly 
classify the game traffic, so maybe attitudes are changing at last. Could we hope this might be done before release in 
the future? I'm not holding my breath.

Legitimacy and design/architecture aside, please note that of the thousands of ports that are specified in the Bugie 
documentation, "only" 3074 UDP and 35000-35099 TCP are required to open INBOUND. Unless you are actually performing 
egress filtering (most hi-ed institutions don't) then the majority of these ports are already open/available.

Best,
alex

A student has requested the opening of a large number of firewall ports (thousands) as referenced at the vendor site: 
http://www.bungie.net/en/Help/Article/11875.  We do not plan to open the ports.  I have never played the game.  The 
request raises concerns that the application has security design issues, and the company has brazen attitudes towards 
security in stating the ports should be opened.  Has anyone else dealt with this and developed an objective rationale?

Kind regards,
