Great, thank you, i managed to change the static IP back to the original setting 192.168.1.10.
The next issue that i am having now is not able to view my CCTV from public network. I am able to view my CCTV(with port 80) within my local network. I have set my DDNS accordingly to my DVR and is connected to my router (DLINK DSL-2640B with IP 192.168.1.1).
I have also set the port forwarding in the router to "External port" start= 80 end=80, server IP address=192.168.1.10 .
I also connect my notebook to this local network. i am able to ping my router 192.168.1.1 and DVR 192.168.1.10. But when i ping the DDNS "pgs5150.dvrdns.org", i am getting the IP address but with timed out messages. i believe the router is not configured properly. Can someone help on this?
