WNDR4500v2 - HTTP Port Forwarding for Multiple Security Cameras Different IP Addresses

[DannyK395]

Greetings! 🙂

I need to forward incoming HTTP requests (Port 80) to different IP addresses on my LAN. For example, I have three security cameras, each with their own IP address. I need internet access to each of them but the WNDR4500v2 throws an error when I attempt to set up port forwarding from 80 to more than one device. That is, if I try to specify ports to the following IP addresses

192.168.1.200:88

192.168.1.201:89

192.168.1.202:90

Only the first one works. The error after trying to add another port (in this instance 89 or 90) says

"The specified port(s) are being used by other configurations. Please check your configurations of USB Readyshare, Remote Management, Port Forwarding, Port Triggering, UPnP Port Mapping table, RIP, and Internet connection type."

What am I doing wrong? In summary, HTTP forward to three devices with different IP addresses is not working.

Thanks!

You cannot forward a single port to more than 1 address.  The router wouldn't know what to do.

You must assign a unique external port for each port forwarding rule.  Since the internal ports are unique, the simplest solution is to use the same external ports.  In other ports, set up 3 port forwarding rules:

1. external port 88 to internal port 88 at 192.168.1.200
2. external port 89 to internal port 89 at 192.168.1.201
3. external port 90 to internal port 90 at 192.168.1.202

Then you would include the external port number in the URL (e.g. https://xx.xx.xx.xx:88).
