Setting up multiple consoles in the same house

If you have multiple accounts trying to access the content, it would be best to purchase it on both consoles.

When you purchase content it is tied to the gamertag that purchased it as well as the console it was purchased on. The gamertag license allows only the purchasing gamertag to be able to access the content from any console as long as it is signed into Live.
The console license is what allows other gamertags to access the content, but the license can only be on one console at a time.

...We're all on the same network, we all have open NAT, ...

What do you mean you are "on the same network"? Are you and your friend using multiple consoles in the same house?

How did you set up your Router to get an open NAT with multiple consoles? Depending on your router it might be a compatibility issue with your router that it doesn't support

Hairpinning or multiple consoles in the same network.

you don't have to re-purchase all the games, but your child must be connected to the Internet if they're not on their home Xbox to access games that are part of your family

Some games I call of duty and I'm not sure but possibly Minecraft or specifically blocked from being shared. This is the same as it always was where you had to have a disc or a cartridge. When you buy a game you're buying a single license to play the game, and the copyright holder has the right to block your ability to have more than one person using it at a time

other features such as cloud gaming are limited to the primary account holder. call family plans have been explored, they have not been implemented outside of a few isolated experiments

If you're connecting over the Internet it requires Xbox live on Minecraft, however you can connect using your local area network for free.

Hello!

Hope you are well. I'll be glad to assist you.

I'm sorry you're experiencing these issues.

Indeed, the way to share content is through the Home Xbox feature and can only be configured on one console at a time.

If each of your children has their own console, the content of the account where the subscription is purchased (account A) can only be shared on one console with other accounts and on the other console, account A must be used, so that the content can be used simultaneously.

I hope the information has been clear, I will be attentive to any questions you may have.

Best Regards.

Hello DAJAXMAN,

Good question, yes you can have two Xbox One's in the same house. If its your girl's friend first time downloading her account to a Xbox One that Xbox One will become her main Xbox. As long as you have one Active gold account downloaded to the system your
gold will be shared across the accounts. in this case her account.

Thank you!
