My dvr http port is 80 by default. So, in my router, I forwarded port 80 to my dvr ip address(internal ip). I was able to view my dvr online through my public ip(static). Now I want to stop this. I deleted the port forwarding from my router. But still my dvr is opening when I access my public ip(static) outside of my network. Plz suggest. Why my router is still diverting my public ip(static) directly to my dvr?

It sounds like you have a router bug or perhaps may have enabled DMZ (demilitarized zone) if that is a feature in your router, this would disable all firewall features of the router. You might want to check your firewall settings, possibly add a rule to block port 80 and test again or forward port 80 to a non-existing IP address so that any traffic to 80 leads to nowhere.
If all else fails you could try resetting the router to factory defaults.

1Sometimes a router restart is needed to get rules updated properly. – DavidPostill – 2017-04-05T16:54:39.900
After deletion of rule for port 80 I restarted the router many times. But canyouseeme.org is also seeing my port 80 on my public ip(static). Dvr is also opening directly if i access my public ip from outside of my network. – john – 2017-04-05T17:05:43.280
Since you haven't published any diagnostic data it is impossible to tell. The question is simply too broad. I don't even know for sure whether port forwarding was needed in the first place. – None – 2017-04-06T10:38:11.563
