Uverse - Pace 5031NV - Can't setup Remote CCTV Access...

Prior to Uverse, I had Comcast Xfinity (not bad, but expensive).  I setup my CCTV DVR access through a Dynamic DNS and it worked like a charm.  The Xfinity RG was hooked up to a Linksys E3500 and that is how i setup a static ip to the DVR and port forwarding was done.

Now, I get Uverse a few weeks (a day before vacation) and the installer says "No Linksys".  So, I hook up the DVR to the unmanaged switch and the switch connected to the router.  I use the Pinholes, DMZ etc. setting to setup an application pointing to the static IP and open the same ports as before.

Guess what?  I cannot access the DVR.  In my mobile phone, i set it up using my RG IP address (whatismyip) and added the port like i would normally, but I cannot access the camera system.

I don't know if anyone understands my post, but i need help.  In a nutshell, i cannot setup my new Uverse Residential Gateway Pace 5031NV to allow port forwarding to my static ip DVR on the network.

By the way, through the RG i can see the ip setup for the DVR and i can access it locally, just not remotely.
