Port Forward IP Address incorrect

Having the same issue below.... My reserved Ip Address is inaccurate when i try to port forward.

"In the Xfinity modem Web Interface I added a device with a reserved IP address. I have verified the device name and IP address are correct. In the xFi interface I added a Port Forward to that device. All good up to this point, or so it seemed. In the Port Forward display it shows up as No Associated Device and the IP address is wrong. I know that's the one I added because it's the only one there and the port is correct. What's up with that?"

Any ideas?

Hello:

We have been experiencing this same issue. Previous to our new XB7 gateway, had static IPs on individual computers, used for port forwarding for remote administration/support. Now that XB7 does not allow port forwarding via its built-in web admin console/interface, been trying to set up port forwarding via the xFi Web Portal. Changed individual computers from static IPs to DHCP's reserved IPs. Then, used xFi to create a port forward to new DHCP's reserved IP. The port forward gets created; however, whenever we attempt to remote into the internal computers, the remote administration/support software does not connect. Then, looking on xFi and/or XB7, the DHCP's reserved IP has changed back to the previously-configured static IP! We just upgraded to Comcast's/xFinity's new XB7 modem/gateway. Port forwarding via our previously-installed Comcast/xFinity modem/gateway worked just fine, prior to upgrading to our new XB7 modem/gateway. Thanks for any information/assistance you may be able to provide us.

Have been having the exact same issue as described in the original post. I assign a port forward to my device, but it gets added under an older IP instead ("No Associated Device") despite the device's IP showing up as the correct value in the website's details on said device. It's as if the interface for adding a port forward remembers the old IP and refuses to acknowledge the new one. Would love a fix for this.

Hi there, Thank you for commenting on the post. Have you attempted to use the xFi app to create the port forwarding settings via an external network first? This issue may be caused because you are connected to the same network you are attempting to create the settings for. I would suggest using the app while connected to its provider's network so that it does not create an issue. Please let us know if the workaround works.

I no longer work for Comcast.

Having the same issue and it's extremely frustrating that this is a known issue with no fix.

@XfinityEdgardo Thank you for the suggestion, though sadly it didn't produce any different results. The xfinity site still thinks my PC has a different IPv4 than it does.

Thanks for letting us know, @user_478379! We are still here to help figure this out with you however we can, so I'm glad to see what I can find for you today! Make sure you've checked out both how to Set Up Port Forwarding on Your Xfinity Gateway as well as how to Set Up Port Forwarding Using the Xfinity App (which it sounds like you've done, I just don't want to miss any possible solutions). I also know that some customers have found it helpful if you Release and Renew Your Internet Protocol Address, so maybe there's something in there that will help you out too. Just let me know if you do find a solution using these. If not, we may need to dive further into your particular account for some in-depth troubleshooting, which we're more than happy to do!

@XfinitySara I have indeed done all that, and tried again. I don't have the necessary hardware to do Advanced Settings, and renewing my IP kept it the same number, but the site still port forwards the wrong number instead.

@xfinity Just let us choose what IP address we want to forward a port to. This is stupid.
