Need Help Port Forwarding my Router

[Sooner535]

I have recently bought the TP-Link ARCHER CR1900 AC1900 Wi-Fi Docsis 3.0 24x8 Cable Modem Router, and am having trouble port forwarding, any advice on how to achieve port forwarding on this modem?

Any help would be greatly appreciated, I have set up a static IP using my router and assigned my PC the same IP, but even with it set to port forward the port, no dice, anyone?
