PTCL Router port forwarding help required

Hello Friends
I have went through other threads but couldn’t find any solution

My network DVR is working at local ip
Using public IP I am able to login to my router but when I configure port forwarding to access this DVR I receive message

This site can’t be reached refused to connect.
Search Google for 111 111 111

I am setting external port to 9080 and internal port to 80,Server IP, protocol TCP
is there something else which I am missing here?


Port 80 and a lot of others well known ports are not allowed on home networks live ips.

Externally make it something like 7000 internal services might be listening on 80

I tried that allready but no use , And my DVR has no option to change its port
