Port forwarding

I want to remote view an IP camera where the main link comes in a Mikrotik router and the camera is connected to the LAN
I need to setup the router to forward port 3333.
Please advise on the way forward.

You have to set up destination nat rules. Manual has the examples:

Hi,
Go to /IP Firewall NAT, and add this rule:

chain=dstnat action=dst-nat to-addresses=<IP camera address> to-ports=3333
protocol=tcp dst-address=<Put Router Public IP address> dst-port=3333
