N66U not getting external IP from RG Uverse Modem

At one point I had this same issue and I read somewhere how to get the N66 obtain a external IP from my uverse rg router. I dont remember how I did it but for a while everything was fine. Now once again the N66u is only getting a internal ip address.

I tried putting the rg in router behind router mode and still nothing. Power cycled everything several time and still no go.

What else can be done other then getting rid of uverse?

Thanks,
Chris
