Xbox 360 NAT Configuration

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.

XBL has had serious issues the past three days. I wouldn't change any router settings at this point.

I went down the same path you did, and couldn't connect after the router setting changes.

Mine is still moderate.

It worked before, so I guess I'm just waiting this problem out.

I did the static IP + port forwarding, with no movement on NAT settings. I kept the static IP, and opted to push the 360 into the DMZ (when doing this, it's key to disable the port forwarding). Doing that enabled me to get my NAT back to open and resume playing games with my friends.
