Alright, here is the deal... I don't recommend you forward each camera to the internet due to known security holes in the camera firmware that allow anyone to get into your feeds, but I can help with the router in the event you still want to do this.
Public and Private UDP Ports = [blank] (these are not needed)
Public and Private TCP Ports = the configured ports you set in the camera settings (Configuration > Basic Configuration > Network > Port > HTTP Port)
Private IP Address = Camera IP Address (Configuration > Basic Configuration > Network > TCP/IP)
The port settings need to be different for each camera and can be ports of your choosing so long as they are not default use for other purposes. I recommend setting up a single camera at a time before trying to get the next one working. Good luck!
Edit: And don't forget to change the usernames and passwords on the cams!!!
