Filemaker17 and exchange server on same network

[D4V1D]

We are using exchange on the same network which uses 443 so in previous version of FM I just changed the port to 4443.

To  get around this I used the router to forward port 4443 to the FM server and change it back to 443. This worked and showed me the databases, the problem is that when I try to login I get a blank page and no login box. I think this is due to the change in ports from the router as it works internally.

The only options I can see to get this working if the listening port cant be changed, is to go back to FM16.

Is there a way to change the listening port within the config files on windows?

Thanks

I have ran macOS server with reverse proxy for years but Fms17 is not supporting other IP addresses anymore. I spent two days on the problem fiddeling in the files but I think it is not possible to run FMS17 on a machine that has any other listener on port 80 and 443.
