Help with disconnection? Not able to port forward on Comcast Gateway CGM4140COM

Hi Pochizzled92,

Thanks for the update. If you call your ISP they can assist you in port forwarding the router. They are able to log in the router themselves. Personally did this myself through Comcast. Just make sure you have the ports needed for the Xbox which are:

These ports must be open for Xbox Live to work:

• Port 88 (UDP)
• Port 3074 (UDP and TCP)
• Port 53 (UDP and TCP)
• Port 80 (TCP)
• Port 500 (UDP)
• Port 3544 (UDP)
• Port 4500 (UDP)

Thanks,

Brad

Check if your NAT is all Open in your Network

Hi there pochizzled92,

Thanks for reaching out here in Xbox Forums. I understand there is an issue with port forwarding for the Xbox system on your Comcast network.

I recommend to create a static IP for the console, and
port forwarding on the network
configuration settings for a better connection.

Check out this article for more information on the Xbox Live Ports.

If the issue persist, we recommend to contact your Internet Service Provider for more troubleshooting and configuring your Network connection and hardware.

Give this a try and let us know the results.

Funny enough, the link is blue for the static IP, which I mentioned I'm not sure if it's the same as a reserved IP - but I also made a post on my ISPs forums to try and resolve the issue but for now set my xbox to a reserved IP, but because the xbox uses
IPv6 I'm still not able to add in ports forwarding to it, but will get back to you when I get more info as I work random hours and have not had a chance to contact them over the phone during the day.

Will let you know if reserved IP helps the issue any, and got my fingers crossed
