Do we need to set the port in mock service and SSL port different port number?

I'm trying to set up the mock service with SSL.

When I set a SSL port number e.g. 8443 and I can't set the port number for the mock service as the same number(8443).

SoapUI don't allow to set the port number that the same port number as SSL port number.

For example: I set the mock service with SSL port number to 8088.

Then I send a HTTPS request to port 8443 e.g. https://localhost:8443

How SoapUI know that the HTTPS request from port 8443 go to port 8088 which have the mock service running on it?

Please suggest.

Thanks,
