Passthrough on 5G gateway

I have the newer ATT NCM1120 gateway and I'm trying to passthrough to my Netgear router. The gateway does not have an IP PASSTHROUGH option. Do I have to use the DMZ setting to get the WAN to my router? Not much on the web about this ATT 5G gateway.

if have DMZ option instead of IP Pass Through, look for setting up 5268 gateway as that was the last PACE gateway that used DMZ.

Pace 5268

From a computer connected to your Wi-Fi gateway:

Go to your gateway settings and choose Settings.
Scroll to Software Version. If you have version 11.1.0.xxxx or above, continue with these steps. If you have earlier versions, you don’t need to do anything else.
Select LAN and then LAN IP Address Allocation.
Scroll to Devices. Check Device Status for one identified as DMZ device.
In Address Assignment, choose Private from Pool or Specific Private IP.
Select the Firewall tab and scroll to Edit firewall settings for this computer.
Choose Add a new user-defined application. You’ll see the Firewall Application Profile Definition window.
In Application Profile Name, enter All UDP and do the following:
- In Protocol, select UDP.
- In Port, enter 1 in From and 50999 in To.
- Select Add to List and then Back.
In Application Profile Name, enter All TCP and do the following:
- In Protocol, select TCP.
- In Port, enter 1 in From and 50999 in To.
- Select Add to List and then Back.
In Select a computer, choose the device you want to forward all traffic to. Or, enter the IP address of the device.
In Hosted Applications, select All UDP and All TCP, then Add them.
Select Save.
