I have got two wireless modems both with DD-WRT firmware on them. I have set one to AP and the other to client. I have no protection on them.
Now when I go to play H@lo and I host a game from the AP router XBOX and then go and look for the game on the other xbox I can see it. But then when I go to connect it comes up with an error saying something about my NAT being open but the settings aren't correct.
I have tried and tried to fiddle with the settings but nothing is working. I'm really at wits end and was just wondering if anyone had any info on this.
I have tried rainbow six vegas 2 aswell. I can see the game but it just won't let me join.
Cheers.
First, they're routers, not modems.
In the post, the use of WDS is mentioned. I have tried this myself (just yesterday in fact) and it's rather deceptively easy to set up.
Using the names of Host and Client for the routers (Host is the primary router, Client is the wireless router connecting to the XBOX) and PC and Laptop (PC connected directly to Host and Laptop connected directly to Client).
- On both routers, make sure you have the latest version installed and disable any DHCP services on Client.
- Hook Client up to Laptop and make sure that Laptop has no connection to the LAN at all. In other words, disable all connections except for the one connecting directly to Client. Manually set the IP address of the Laptop (example 192.168.1.10) and then browse the Client.
- On each router, go to the Wireless/Basic page, ensure that both routers are set to the same channel. When I tried to have Client set to automatic, thinking it would find the Host channel, I had problems. It didn't quite work out that way.
- Go to the Wireless/Security page and make sure that the security is either disabled or exactly duplicated on both routers.
- Now on both, go to Wireless/WDS. Each will have a MAC address listed at the top of the page. Find an available entry (should be the first one) and change the option from "Disabled" to "LAN" and then copy the MAC address from one router to the other. (IE, copy the MAC shown on the Host to the Client and vise-versa).
- Try to browse from the Laptop to the Host and from the PC to the Client. If either or both fail, power cycle the routers. If it still isn't working, let me know and I will help you figure it out.
Once you have the WDS setup, connect the XBOX to it and go to the Network settings. If the IP address starts with a 169, then try manually setting the IP address and Subnet Mask. Then test the connection to a computer (to see if the network is working). Once you have a successful LAN connection, change the IP and DNS back to Automatic (if it was Automatic before) and then test the XBOX Live connection.
Works for me and haven't had a problem yet.
