DCS-920 on TL-MR3220 Remote View Settings

Hi,

Anyone knows how to do remote viewing setting for a D-Link DCS920 on a TL-Mr3220 using 3G network?

I have tried setting the TL-MR3220 port forwarding using port 800. Set the static ip address for DCS-920 and the port number 800.

Gotten the ip address and added :800 but it did not work.

I can view the router from remote but not the camera.

Everything is viewable within the wireless network but not remote.

Please advise.
