two xbox one consoles on the same network joining games problems

Hello! My roommates and I are having the same exact as above. We have tried the above steps, and similar to the aforementioned... we all work in IT / Cyber so we have tried the normal fixes. I have tried some searches but it doesn't seem like there is much
of a solution. Any ideas on how to get this to work?

All our NAT types are set to open. We are all connected to the same internet. All the above mentioned comments apply to us as well. We're really hoping to be able to play together.

Thanks!

I am playing COD Modern Warfare, and for the life of me I can not figure out why my brother and I can not play online together. The only way we can play online if there is a 3rd person at their house that adds us to their game. So in total, there are 3
people in the game.

-We can, however, join each other's party.

- We can not join each other's games

-We can not invite each other to online games.

I have looked everywhere on this site. Please help.

Don't tell to check the internet, mesh systems, wired versus wireless...

One is wired

One is wireless

Both have the game.

Both have Xbox live.

Both have been updated.

What is the problem?

I used to have this problem sporadically on both Xbox 360, and the Xbox One since we have always had multiple Xbox consoles in the house. It's usually due to NAT settings, and both of you not being set to "Open".

You can check your NAT settings by going to your Network Settings on your console, it should state your NAT Type on the right hand side of the screen. If both, or either of you aren't set to Open, then you'll need to open some ports via "Port Forwarding",
there's a list of the ports you need to open at the following link: https://beta.support.xbox.com/help/hardware-network/connect-network/network-ports-used-xbox-live

Hopefully that can help solve the issue for you both.

Hi,

Are you able to see what you NAT type is in game?

Multiple consoles on one router are only able to use UPnp to get connected simultaneously. This usually gives a moderate NAT, which in most cases is enough to play online together. Only known exception to me is CoD where you cannot join the same game lobby
due to the special network implementation of CoD itself.



@Monitor Chakas

The problems with getting disconnected from the destiny server is afaik a known problem with their servers and not your network environment. I know several people (couples) playing together coop with moderate NAT without problems.



@Jimmyakaskippy

Your problem is the teredo filter of your router. I posted you an answer to your problem in your own post on your issue.



@Slaggg

Unfortunately an IPv6 connection is not solving the problem but can make it even worse. There are routers which are unable to serve two consoles by UPnp simultaneously. There is a list with routers in the network hardware section of this forum: forums.xbox.com/.../default.aspx
where you can check für your router.

Please keep in mind, that it is not possible to configure portforwardings or DMZ while using more than one Xbox in the same network, no matter of its a One or a 360. It's also not possible to play on two One with the same gamertag at the same time.
