Party Chat. My ports are open and I have IPV4 on my router, but I can´t access the party Chat.

Funny thing is that my X360 shows OPEN NAT and my XB1 shows STRICT NAT. I have all of the correct ports open on my router and my party chat only works some of the time on the One.

have you logged into your router, and tried to open up the correct ports to enable party chat?

the link was because of the blocked incoming connections. I know that I can disable the teredo Filter and then all works fine and my NAT is open. If I enable the Teredo Filter as suggested from AVM then I can play games like Neverwinter for example but I
can't join xbox live partys.

If it si possible to have NO Teredo and use Party chat (doesn't it work over Azure Servers? Then it should be no Problem?) and in games I can only find other IPv6 Users that would be fine - I don 't need the IPv4 users to game with. But then I have to know
if I need to open Ports on the Firewall or not.

When I enable the Teredo Filter my NAT is strict - thats why I also ask for Port Forward

After opening up the port for my router it is still having the same party chat issues as before and in game chat for Battlefield 4 is absolutely terrible. It has to be a software issue on Micros part. Hope it gets patched up in a timely fashion.

I have the same problem: coudn't join party chat nor automatically disconnect myself after I invite friends to my party.

my NAT type is open and has no problem with my network and router (Teredo interface enabled already)

and I figured it out that it is due to the accident shut down during the gaming last night, after I completely reboot my xbox one, I can join the party chat now. hope this helps.
