Amid the other problems I’m having with my Xbox 360 and Xbox Live, this morning I seemed unable to recover my gamertag. When I did the network diagnostic, I found that the NAT settings came up as “Moderate” (on the Xbox Live scale of “Strict,” “Moderate,” and “Open,” you really need that to say “Open”).

To make it read “Open,” you need to forward the following ports through your router to your Xbox (which means you’ll also need a static IP address on your Xbox):

• UDP 88
• UDP 3074
• TCP 3074

Lucky for me, PortForward.com has some great free how-to articles on setting up just that. Here’s the guide to setting up a static IP address on your Xbox 360 and the guide for Xbox Live port forwarding on a Linksys WRT54G.

Interestingly enough, after futzing around with this and getting it to a situation where I couoldn’t even connect to Xbox Live at all, I put all my settings back the way they were (remember they were “Moderate?”) and suddenly it was seen as “Open.” I guess you never can tell.
