You will need to follow the process below to set up a port forwarding for Minecraft on your AT&T network: Ways How to Do AT&T Port Forwarding In Minecraft Minecraft servers can be hosted if you have the PC specifications capable enough to take the load and process all the data that is coming through and being sent on the server. But what we are going to help you with today, is how you can use port forwarding on the AT&T network to host a gaming server for your Minecraft. Through port forwarding, you can access your home surveillance camera or a device remotely as well, or use remote access to your home computer. It also enables you to host photo-sharing hard drives that allow you to access the data on your own hard drive remotely, anywhere in the world. Port forwarding is an advanced subject and most people will not need to use it generally but it is highly useful under some circumstances such as running a sling box or streaming media devices. You are setting all the rules for this data being sent or received on a specific port to a specific IP address on your home network. You basically set up a gateway that routes this data to where you want it to go, in this case, a remote device. You might need to understand how it works and how you can set it up. Although, the system is not complicated at all. Port Forwarding is basically a method that allows you to access the incoming and outgoing data on your home network or devices from a remote location. But even if you are a beginner and want to learn the basics of port forwarding and how you can set it up to make it work on your AT&T network. I have attached two screenshots one with the playback error, and the other is the attempt to access via the channels link on my DVR webpage.If you are a Minecraft fan and you want to host your own server, you must know all about port forwarding and how it works. My access has been thru my ATT LTE connection on my iPhone and iPad, not my home network. Also, when I attempt to play a recorded show on my iPad, via the DVR page, I get playback errors. My problem is, when trying to access the router using the links provided on my Channels DVR web page, it goes nowhere.

So I know I have access to my router, as I am able to get in using the public IP with the port number.

I read online that your particular router doesn't support 'nas loopback', so the port forwarding doesn't work if you try to access it within your house. Were you accessing your IP over your home internet, or using cellular connection?

I did enable remote access in the DVR settings, but attempting access thru the public IP/8089 results in a 'Safari cannot open page' error.
