XB8 gateway issue

The XB8 firmware is blocking Xbox

UDP traffic.

My logs show FW.IPv6 forward drops, and the Xbox multiplayer test fails with error 0x000000000000000.

I need IPv6 routing disabled or the IPv4-only gaming profile applied.

When I search these forums there are a lot of people affected by this and Xfinity seems to not [Edited: "Language"] about fixing it. I have already had a tech come to my home he couldn’t figure it out . Than I was stuck on the phone for 3 hours with advanced tech support and they still could figure it out either . When I check my gateway logs under firewall I can see the gateway blocking the IPV6 port which is what the Xbox gaming console uses to play multiplayer online. I have internet access to the Xbox and can download load games but the multiplayer online is being blocked by gateway. The new firmware xfinity has pushed out to the gate way has caused this issue . I need help

Hi user_z4lxa6! Thanks for visiting our Xfinity Forum. We appreciate you being a customer with us, and I am sorry to hear about the issues you're running into with Xbox multiplayer. I see you have tried many avenues of support for this and stated you had a tech out. Can you please tell us a little more about the results of that visit? Did the tech confirm this is not something we can fix?

Was there any new update on this issue? I just switched from my own modem to an XB8 and have been regretting it. I’ve had issues on both Xbox consoles and my gaming desktop.

I just wanted to comment that I am experiencing the exact same issue. I tried the same troubleshooting steps, hard resetting both devices, disabling firewall, disabling all security settings I could, check that uPnP is enabled, manually port forwarding Xbox/Microsoft ports, etc. and NOTHING is resolving my issue. I agree with the above user, I need the following:

Confirmation that this issue is under investigation by Comcast engineering.
A timeline or firmware version number for the fix rollout.
Billing credit consideration for loss of Xbox Live multiplayer functionality.

Get a router that is under your control and not controlled by Xfinity firmware or software pushes. I do have an XB8 because of a favorable pricing scheme, but I would not consider using it in anything other than bridge mode.

@user_z4lxa6 did you try using a router that allows you to disable IPv6? I just spent 3 hours with a supervisor technician trying an XB6, XB7, XB8, etc and we tried port forwarding, disabling firewall, manual port changes, etc everything we could think of. The tech was totally stumped, but I’m going to buy a router that allows me to disable IPv6 and use it in bridge mode.

No I haven’t tried my own router . I’m going to get one soon but you should not disable IPv6 your Xbox multiplayer gaming needs this to communicate to server to connect to multiplayer gaming port . The issue is in Comcast network cloud blocking the IPv6 . If you see my post in the past if you login into your router via 10.0.0.1 and for the diagnostic logs you will see your IPV6 port being blocked by firewall from router . I assume your own router is doing this but since you just like I have tried all there router even there old legacy ones like the xb7 and xb6 I was told from a technician that there cloud firewall is automatically setting protocols to there gateways via a Xfinity cloud service for there gateways and network . Just look at there logs you will see the port being blocked this is why Xbox multiplier isnt working for so many of us. Again Comcast refuses to do anything about it and I have been in talks with a lawyer for a class action lawsuit . Will see if they get off there [Edited: "Language"] and actual do something . Also you must go to advanced setting and reenable the UPNP on the xb8 router . You should be able to temporary play some Xbox live games buts its spoty at best. The UPNP setting on my xb8 automatically and randomly sets it self off and crashes my online gaming for my PC . My Xbox consoles still has issue on Comcast network . I think a Class action law suit might be the best option at this point. Comcast has not even reached out to me since October 14 about my issue being resolved . Worst company I have ever had to deal with . Hope this helps in anyway and best of luck with this [Edited: "Inflammatory"]
