I have same problem. Tablo ethernet connection to Xfinity modem/router gateway. Ports configured using Tablo app to recommended manual port settings, 80 to 21xxx, 8887 to 21xxx, protocol tcp/udp, reserved ip address 10.0.0.xxx( question: why is my device ip different what is posted here?) Remote access enabled and everything works fine for 24 hrs, then remote access lost. Call my sister where Tablo located, 1500 mi away, ask her to disable, then re-enable remote access using her iphone Tablo app. Message remote access enabled immediately appears and my remote connection is resumed. Have to do this everyday, getting old. Have seen suggestions to disable advance security feature on gateway, turn off udp protocol in favor of just tcp. Checked and public IP of Comcast not changing during problem, even though they are known to use dynamic ip’s. See many others here have same issue. Neither Comcast tech team nor Tablo support have been able to provide an answer.
