I would recommend that you avoid port 80 for your camera and use port 8081 for example. Also it helps if the camera will allow you to set up a static IP address like 192.168.1.50, as it make port forwarding more reliable. You can create an application for port 8081 and call it webcam.
IP address 192.168.1.50
Subnet mask 255.255.255.0
Default gateway 192.168.1.254
You will be able to see you camera by typing 192.168.1.50:8081 into your web browser.
