USG 20W - Port Forwarding not Working Locally

I'm new to Zywall USG 20W but have never had this issue with other routers including Zywall 2 Plus.

I have ports forwarding to a DVR. I can view the DVR from anywhere in the world using »*ip-address-here*:*port-number-h ··· r-here*/

Anywhere other than on a computer on my own USG 20W LANs (LAN1, LAN2, WLAN1, etc.)

I'm created a service called DVR that specifies the desired port.

I have NAT type virtual server, interface WAN1, original IP any, mapped IP to my DVR, both ports set to my DVR service.

And I have a firewall rule to allow my NAT through form anywhere sending this port's traffic to my DVR.

it works form the outside world but not from within? What am I doing wrong?

Oh and the reason for this is so that a smartphone app may view the cameras with the same settings from the outside world or at the location.

So I want to be able to use the IP address or a dynamic DNS address to forward the right ports to my DVR... whether I am on wifi or LAN right next to my DVR... or another LAN, 3G, etc... With most routers this seems to automatically work but I somehow hit a snag with the USG 20W...

Well If am on the outside, I probably try to access my DVR using a WANIP address (or an url associated with a dyn address aka dyndns.coms service.

If I want to access the DVR from within the LAN I would use its LANIP address.

There is also a loopback function which you can invoke for the virtual server rules which may allow you to do what your attempting (simulating outside looking in).

As mentioned, in NAT you have to enable "NAT Loopback" for every single virtual server you define.
On Z2+ NAT loopback is on by default, on USG is not.
