1:1 / Full Clone NAT

Hello Guys,

i need to open two Ports from external access (WAN) to my internal server via our public internet-address (example.com).

The ports are 8100 and 40000, the server is 10.10.10.248.

Another employee needs to access our public internet-address with this ports to access the server (some SAP software), like https://example.com:8100 and https://example.com:40000

How can i open this in the FortiGate FW?

Thank you,
