Solution :

There’s no way, without using port-forwarding (or something functionally equivalent under a different name) if you are, as you almost certainly are, using a router that is performing network address translation (NAT).

If you have control of an external endpoint you can probably establish a connection to it from the IIS server using tools like netcat or socat. You could then use this established tunnel to communicate with your IIS server.

If you can set up a VPN – this would also allow access.

If you have IPv6, there is no need to port forward (but you will need to make sure the edge firewall/router isn’t explicitly blocking incoming packets). In most software, you can listen on ::0 to mean “all IPv6 interfaces” – otherwise you can hardcode your public-facing IPv6 address.
