after beating my head against the wall for a couple of weeks and several calls to Comcast I think I may have stumbled upon a fix...
In the 10.0.0.1 router managment, under Connected Devices...change the device from DHCP to Reserved IP. You may have to change your DHCP range before you can change it.
Once I changed it to Reserved IP, I was able to add port forwarding from the web app. Hope this helps.
THIS IS THE SOLUTION! I too was beating my head against the wall until I tried your suggestion.
Thank you so much!
