If you want to connect directly to your camera (without going through an eventual manufacturer website) you need to setup IP and Port filtering.
Please note that you will not be able to access the camera using the forward from within your network. To test if it is working you have to be connected on an outside network. (You can use your mobile for example, just deactivate wifi on it)
P.S. If you have activated "Remote access" on your Connect Box you should quickly disable it. This is only to be able to access the Connect Box from outside your network and is absolutely not recommended nor useful.
