XBox Live problem - 2wire NAT is not open

I just got Uverse yesterday. I discovered that my NAT is moderate, which prevents me from joining my friends in games. I tried forwarding all the ports that microsoft reccomends... hasn't worked. Any input?

I think the one thing we know for sure is that in gregzoll's mind his opinion is law Smiley LOL


No, it is that I know what the Frick I am talking about, when it comes to hooking up these game platforms to routers, and the security risks involved with opening ports out of Stealth to the Internet for all to see possible ways into your LAN.

Gregzoll_1,

 

After reading your responses to this thread, I'm now of the opinion that not all A.C.E. recipients are created equal. I find the other award recipients very helpful to this community, but you've now made my "ignore list." (It's a bit inaccurate to call it a "list" since there's only one name on it.)

 

The original poster seems to have disappeared from this sorry thread. I assume he's gotten his Xbox issues worked out. And I'm finished trying to correct misinformation.

SomeJoe,

 

Thanks for your thorough analysis. For someone who doesn't even have an Xbox, you obviously put a lot of time into researching it. I don't know as much about networking as you do, but I did find this article about Port 53 and why at least that author recommends opening it to deal with future IPv6 DNS replies, among other things. I don't think IPv6 support has been implemented in the U-verse RGs yet, so AT&T may address the issue discussed in the article in any firmware update that implements it. Additionally, I'm not saying this is why Microsoft recommends opening Port 53; I don't know why they do.

But I completely agree that you should only open those ports that are necessary to get the Xbox working properly. I'm not aware of any reported instances of an Xbox-connected system ever being compromised with the ports open in the manner recommended by Microsoft, but if not opening Port 53 works, then so much the better.

Hi Ponzi,

Yes, the article is correct about allowing port 53, both TCP and UDP, for proper DNS operation with DNSSEC and IPv6.  However, this only applies to DNS servers which are behind a firewall, not DNS clients.

 

The XBox's use of port 53 (just like any other computer on your home network) is limited to DNS client functionality only.  In other words, the XBox asks a DNS server out on the Internet to resolve a host name.  This is an outbound connection, and the port will be opened automatically on any NAT router for both TCP and UDP connections, as well as IPv6 connections when that gets implemented.

 

No requests will be incoming to the XBox on port 53, so we do not need to manually open the port.

That article is not written by Microsoft. It was written by someone who has been in the industry for around 14 years, stating their opinion. No where in it, does it imply anything regarding Microsoft suggesting the opening of Port 53.

Ponzi, you may want to actually read the article, along with the other links the party that wrote the article you linked, to get a better understanding what they are talking about, and why they are suggesting this work around for IPv6.

SomeJoe,

 

Thanks. Got it. Didn't see that the article applied to servers only.

Darn, wish I would have found this earlier. I had to figure it out, but it is exactly what I did. Thanx SomeJoe for posting the detailed instructions for others.

I am guessing that Greg does not run multiple gaming consoles at the same time nor does his son actually try to join someones game.  I am having the issue of haveing one open NAT and one strict NAT.  I can open the ports but it seems to only allow me to assign it to one of the xboxes and not both as if I try to assign the setting s to both I get an error stating those settings are already assigned.

 

Sooooo doeas anyone know how to get an open NAT for 2 xboxes at the same time? 

 

Thanks

A port can only be assigned to one internal address at a time.  Think about what this does techincally, and you'll understand why:  An unsolicited connection arrives at the RG.  It has the RG's public address and a port number.  The RG has to decide where to send it.  It has no other information than the port, so the port has to tell it where to send the packet.

 

The only way around this would be to purchase a package of static addresses.  Then you could assign a static address to each XBOX.
