Max Br1 Pro and IP passthrough and port forwarding

Hello. I recently got my new Peplink Max BR1 up and running, but I am trying to get the port forwarding to work and not sure what I am doing wrong. I have it in IP passthrough mode and its connected to my personal home router, Netgear Nighthawk XR700. I have created a set of port forwarding rules in the nighthawk but when I check the ports every application I try says those ports are closed. Do I need to create a rule in the peplink as well even though it is in passthrough mode? Most of the online port checkers show my external IP which is given by the Peplink. My port forwarding rule in the router is set up with the internal IP of my computer which I am trying to port forward on.
