Hello,
I am living in Chicago and currently reside in an apartment building where the internet comes through an ethernet port in the wall. I have recently purchase an Airport Extreme for my new Xbox One because my old Linksys WRT160n was outdated and refused to install any new firmware. I have been unable to connect to multiplayer for any game since I bought my Xbox One on day one because of a strict NAT. I do have a network connection which allows me to use Live however, the system always tells me that the Teredo IP cannot be found when I test multiplayer. I believe this is due to the face that when I test what my IP is, it brings up a 173 number. However, I go to my router and it says that my IP is a 192 number. I am not very savvy with this information so what is the step that I need to follow to allow this connection to work? Contact my ISP to get a private number? Do I need to say or do anything specific to get this private ISP? Does it cost additional money?
Any help would be greatly appreciated by anyone who has had a related issue. Technically my building does not condone the use of online video games however I was always able to play online games without a problem on my 360 and never experienced any lag. If you can provide clarity with this I would be grateful! I have tried every other way to get things working (UPnP, IPv6, DMZ & ports). No luck!
