First, make sure the Unite Explore's UPnP mode is enabled.  To do that:

  1. On a laptop or smartphone connected to the hotspot, use a browser to log in (http://attwifimanager/, password is attadmin)
  2. Select Settings > Router in the left-hand menu.  Then select the Basic tab.
  3. Click the On button next to UPnP
  4. Click Save at the bottom of the screen
  5. Reset your gaming system and see if it is connected OK now

Next, configure the gaming device with a static IP:

  1. On your gaming device, look at the current DHCP assigned settings. Make sure to write these down as you'll need some of the settings later.
  2. Check the range of the DHCP pool on the hotspot (Settings > Router then the Basic tab).  You'll see it's something like DHCP IP Range 192.168.1.20 - 192.168.1.99.  
  3. Choose an IP address outside of the DCHP pool's range.  That is typically one in the range 192.168.1.200 - 192.168.1.254.
  4. Enter the IP address that you chose for the gaming device's static IP.  If you have to enter other addresses (e.g. gateway, net mask, etc.) duplicate the ones that you saw in step number 1. NOTE: You may need to do some research to find where to set these settings for your gaming device.
  5. Save and reboot the gaming device
  6. Make sure the gaming device connects to the hotspot and that you can access the internet.

Finally, configure the port forwards on the Unite Explore:

  1. On a computer connected to the hotspot, open a browser to 192.168.1.1 and login using admin or attadmin as the login password.\
  2. Click on Settings > Router then the Port Forwarding tab
  3. Click on the Enable button
  4. For each port you open, enter
    Label - can be anything, like "Gaming Rule 1",  
    IP Address - the static IP address of your gaming device,
    Port - the port to forward (see list below),
    Protocol  - Select TCP or UDP from the dropdown list depending on what the port list shows for the port,
  5. Click the + button to create a new row
  6. Repeat steps 4 and 5 for each port.
  7. When finished, double check that you correctly entered all of them and click on Save at the bottom of the browser window.
  8. Reboot your gaming device and check the NAT Type
