What is the port that your DVR/CCTV allows for browsing? It could be that Airtel is blocking incoming SYN packets -- see ref <http://en.wikipedia.org/wiki/Transmission_Control_Protocol#Connection_establishment> try 'telnet 122.165.84.54 <DVR port>' and see if you get any kind of response. BTW, there is no response on ports 80 and 443 - save yourself the trouble if your DVR is already configured on one of these ports. It could be that Airtel is blocking incoming SYN packets ref <http://en.wikipedia.org/wiki/Transmission_Control_Protocol#Connection_establishment> in which you are out of luck with your current ISP plan. You may have to go cough up more money, for a business grade service (servers allowed on your premise).
