But port forward discussions are legendary. I will not go there but share a common fix for this one I use. Ready?
Put the device you need this into the DMZ of the routers.
What I need to accomplish:
I have an xbox 360 and an xbox one.
Xbox Live the following ports opened for both devices (which may, sometimes, be used at the same time):
<span>• Port 3074 (UDP and TCP)
<span>• Port 53 (UDP and TCP)
<span>• Port 80 (TCP)
<span>and for Xbox One:
<span id="INSERTION_MARKER">• Port 500 (UDP)
<span>• Port 3544 (UDP)
<span>• Port 4500 (UDP)<span>
<span>I am using ATT Uverse as my ISP.
<span>The problem I'm running into is that ATT's user interface for the router (that I access at 192.168.1.254) will only allow me to designate a port forward for one device.
