Passthrough HTTPs traffic to server

Hello, I’m having issues configuring my Pepwave MAX BR1 Mini to pass traffic from the external IP to a website server on the LAN. I have tried a few things and regardless of what I set for inbound firewall rules and port forwarding it just doesn’t work.

For example, let say my external IP is 166.555.555.54, and my internal server IP is I want to access my server over 443 but with the external port as 444. After all is said and done I should be able to go to a web browser and view the website on IP https://166.555.555.54:444.

Is there something else on the Pepwave MAX BR1 Mini I need to configure outside of FW rules and Port Forwarding?
