xbox live loses connection through one of my friends

i'm a online gamer with a few friends.
when one of my friends, living 200 metres from me, is joining in the livechat it's fine, but when he joins a game i'm in (gtaV, Black ops 2),
i get completely kicked from xboxlive, he can't join through my name, he needs to do it through another friend or on invitation.
to solve the kicking problem we allready tried a lot: completely new cables, wifi connections, i've got a new modem, walked through all our preferences again

both our NAT are open, and both have no problems while gaming with other friends, or unknown.
we both forwarded the neccesary ports as shown on internet.

What Country/State/Province do you live in? Holland / zuid holland
Modem brand & model number: ubee evw321b
Router brand & model number: ubee evw 321b
If Wireless, are you using a white or black external adapter, or an internal (Xbox 360S) adapter? internal

Is UPnP Enabled? Yes/no/Unknown: Enabled, but tried both

After you run "Test Xbox LIVE connection" press “Y” for "More Info”. In the pop-up that appears, what are the following values, if shown? (If a value below does not appear for you, just leave it blank.)

Hey there Haag,

Sorry to hear you're having issues playing with your friend.

From the codes that you've linked it looks like there is a an issue with the DHCP lease.


You may want to try setting up a DHCP Reservation for your console. You should be able to do this using your Device's User Manual. Unfortunately it is a pdf in Dutch so I can't translate it and find the exact steps for you.



Please let us know how that goes and we'll work from there.

Hey Haagsevossie,

The error code you're facing means that your NAT is getting a error.

I suggest that you re-port forward the required ports, if necessary using This Tutorial.

Also, make sure that you turn OFF UPnP. This causes issues with the ports.

Let us know if doing these things fixed the current issue =)
