[b]Hello. I found this on Bungie's website:[/b] GETTING CONFIGURED: A GUIDE TO CONFIGURING YOUR NAT SETTINGS. What can UPnP or port forwarding settings potentially solve? Frequent BEAVER/FLATWORM/LEOPARD KTOs Unable to hear voice chat from other players in your own Fireteam Frequent empty towers Matchmade activities failing to find a game, resulting in ‘unable to find a match in time’/MONGOOSE errors If you aren't experiencing these specific problems, we strongly recommend that you don’t mess with port forwarding as it is a delicate procedure that may worsen your situation if done incorrectly. Q: What does NAT mean? NAT is your Network Address Translation. If you're interested in knowing more, there are numerous sites that provide additional information. Essentially, your NAT type represents how easily your console can talk to other devices across the internet. What matters for your Destiny experience is that certain NAT types prevent certain game features from working optimally. If your NAT type isn’t ideal, we have guides to help you resolve the issue. Q: What are the differences between NAT types? Open or Type 1 NAT – Nothing is getting between you and your connection to Destiny. You get the best experience using voice chat, joining games, and matchmaking with players. Note: Open or Type 1 NAT may not be possible in many configurations, especially if you don’t control all of the hardware between you and your internet access. Moderate or Type 2 NAT – This is the most common configuration. You may experience longer matchmaking times, issues with voice chat, or other problems. Strict or Type 3 NAT – Strict or Type 3 NATs often indicate your console network settings are restrictive. With Strict/Type 3 NAT types, we have a harder time giving you the best possible experience, including voice chat with all players in your Fireteam. A Strict NAT or Type 3 NAT is not recommended and may cause noticeable problems. Q: How can I change my NAT type? In addition to changing your console’s network settings, in order to get an Open or Type 1 NAT connection you will have to change your home network settings. Check out the guides on http://portforward.com for information on changing your network’s NAT type. In order to get an Open/Type 1 or Moderate/Type 2 NAT type, you may also have to set up a Static IP Address on your console. Check out the portforward.com guides on how to do that for different consoles: http://portforward.com/networking/staticip.htm [b]for more information on the article, head to http://help.bungie.net and search NAT[/b] [b]Hope this helps.[/b]
