How do I setup BGW320 router with my 5 static IP block so that my other router gets a static IP and continues to route

@JefferMCThis message below from this thread a year ago sounded close to what I am looking to do. Base on this I would have said what I am looking to do is "give WAN side of my router one of my 5 public IP addresses and let it handle the world behind it." Can you please provide some specifics on how to go about this? From what I can tell it seems like I need to utilize the cascaded router settings, but I have not been able to find any clear documentation explaining how to do this.  What I received from ATT looks like this:
I have tried a few different things, but so far the only way I am able to get the internet working, is to have my old router in bridge mode. Any help or direction would be GREATLY appreciated. 
Thank you

"You could give WAN side of your router one of your 5 public IP addresses and let it handle the world behind it.  It can perform NAT from its private side to the WAN address.  You can do port forwarding in your own router.  "

...

Which of these sounds closer to what you want to do? Feel free to ask more specifics.

Is anyone able to assist with this question? Hoping the lack of response so far is just because it was a weekend...

I was able to get this to work eventually

  1. Connect cable from modem to router
  2. Ensure that the UDMP and the Gateway don't use the same subnet for their LAN (if both at 192.168.1.0/24, move one off to 192.168.2.0/24 or something else).
  3. Set up IP Passthrough mode with DHCP-Fixed to the UDMP.
  4. Turn off any additional filters you don't want the Gateway doing in Firewall > Advanced
  5. Reboot the Gateway and the UDMP.
  6. Turn off Wi-Fi on the Gateway
  7. Set up the desired port forwarding in the UDMP.
