To be honest I am not a fan of UPNP. Maybe you could try deleting the UPNP created forwarding rule for the DVR and add your own. A quick google of 'Port Forwarding home hub 2.0' will show you how.
A quick portscan of your IP shows ports 80, 8080, 34567 and 33333 as all being closed so clearly the DVR is not visible from the internet at the moment.
I suspect that Arash is right that the rules are not forwarding those ports to anywhere on the local network
