Hi, 
  
I am from India. 
I am trying to configure my DVR so that I can view it from anywhere in the world remotely. 
I have a Hikvision DVR at home model: HVCDS7104HGHIE1. 
I have connected a straight type cat6 cable from DVR to my WiFi router which is Dlink DIR-600. 
The WiFi router is further connected to Dlink DSL-2720u adsl modem. 
I created a device name on www.hik-online.com, I entered serial number so that it can detect the DVR being online. 
I also entered customized static IP 192.168.1.* in DVR and forwarded port number 81, 8000 and the rtsp port on my Router(port forwarding) and modem (virtual server) using the above static IP. I changed the HTTP port to 81 on the DVR. 
Now when I enter the ddns address on my mobile or any other pc, google chrome says "ERROR_Connection_refused". 
and when I type ddns address in the browser, it redirects me to some random dynamic IP and gives the above error. 
I have BSNL Broadband. 
Can any one please help me with where am I going wrong?
