Xbox – Stream Xbox One game content to another tv

SmartGlas does not require port forwarding to my knowledge as it should work using HTTP which, ideally, should already be correctly forwarded by your router. However, specific games require specific ports to use SmartGlass as companion applications. You should check these game's pages for more information.

All in all, there is a bigger flaw in your plan. SmartGlass has been designed to work on LAN, not WAN. Your IP is likely not static making it pain to keep track of it. And even if you could track it, the IP might not be public and your ISP may have therefore made it impossible for you to remotely connect to your LAN. I believe your best bet is to try and establish a Virtual Private Network. Still, I think the endeavour is highly doubtful.

What would you like to use this for if I may inquire? There might be an easier way to accomplish it.

You can use the game streaming option in the Windows Xbox App to a PC to Windows 10 Remote Desktop on Android if you have Windows 10 Pro. Like Parsec, you will experience lag as the stream passes through an extra--and ultimately unnecessary--machine.

Yesterday Microsoft informed its customers that Windows Phones will be discontinued. Hopefully now they will be inspired to deliver an in-house low latency solution allowing Xbox One content to be streamed directly to Android phones over a local network.
