Adding a second router to network. Can I give it a public IP address?

[ Edited ]

I just bought an Asus RT-N66W router. It has plenty of great features which I would love to use. One of those features is using a DDNS server.

 

The issue is that my Asus router has a private IP address given from the AT&T Uverse Modem/Router.

 

Idealy I would like to disable DHCP entirely on the uverse box and just serve the public IP address to my Asus router.

 

I called AT&T for support. They quickly transfered me to support line in which I would have to pay +$16/month. (?!?!) For them to help me.  

 

 

Network Setup

 

Internet > Uverse Box > Asus Router > Computers

 

For the moment I've placed the router in the "DMZPlus" zone. so that I am at least not going through 2 firewalls. 

 

I've been wondering if the Cascaded Router feature might help,

 

Is there something I might be missing? 

This was much easier to set up back when I had Time Warner...

The DMZplus mode means that when your router makes a DHCP request to the RG, the RG gives it the public IP address.

 

This is probably exactly what you want.

DMZ Plus mode did work. I just needed to reboot the router!

 

Thank you guys for the response.
