Manual port forward instructions & sample image for sample images.
Tools -> Options -> Advanced -> Firewalls, select manual port forward, type in port 64049 for example in each listening & connection ports. Click apply & ok buttons. Then go to file menu -> Disconnect. Then go back to file menu & choose Connect.

The connection port number option box will not be able to be typed/copy-pasted into unless you select the Manual port forward option.
