Netgear router port optoins

Hello,



I have a netgear router (N600 WNDR3800) that I am trying to get port forwarding set up on so I can get remote access to my Dahua nvr (G4-4K-8) using an Iphone. The router only gives me the option to open ports 80 and below. When I try to open ports 81 and up in the router, I get a message that the ports are being used by other devices and that I should check USB Rapid Share, Remote Management, Port Forwarding, Port Triggering, UPnP Mapping Table.

The Dahua NVR only gives me the option to use the TCP ports 1025 to 65535.

Any ideas how to get the netgear router to let me use ports higher than 80?



Please help

Thanks



I didn't find the right solution from the Internet
