For allowing incoming PPTP connections in WG you must configure 1-1 NAT for the server.
When you configure 1-1 NAT, you only indicate to firebox that it should use one specific public IP for all incoming/outbound traffic for/from this internal host.
If you do not configure any incoming service with 1-1 NAT then no incoming traffic would be able to reach to the server. Please note with 1-1 NAT FB only changes the way it does NAT for the machine and not the way it provide firewall protection.
For having windows VPN server which used PPTP, you should use the packet PPTP Service and configure it as below:
"Enabled and Allowed"; from ANY OR specific-ip-OR-subnet; to 1-1-NAT-ip-of-server
To add 1-1 NAT depending on software version you have it would be either under Setup or Network menu.
Please let know the software version and we would be able to assist you further.
Thank you.

You should be able to do the 1 to 1 NAT within the service you are adding. That just opens up the ports associated with that service. If you need to open up ports that are not included in the standard list of services.....create a custom service, add ports that need to be opened, and then setup the 1 to 1 NAT within the services.
