I guess, both are NOT in the same network.  
Install mosquitto or some other MQTT broker on either side (Rasperry Pi or Windows), but secure it with password AND TLS. Then forward a port (either standard port or any other) for MQTT from your router to the device with the broker. Use a static public IP or a DYNDNS service to get the public IP of the router, which made the port forward.  
Then subscribe on one side and publish on the other side. One side locally, the other side over the internet.

If the devices are all on the same LAN, install Mosquitto on one of the Pies.  
Otherwise use a cloud based MQTT broker such as hivemq.

If you are not familiar with securing services over the Internet, I would strongly recommend that you try to use some kind of secure tunnelling service instead if you can.

Also, read the FAQ on security:

> Update 2025-02-19 The best advice for most people doing home automation is still: Don't expose Node-RED to the outside world! Where you really have to have some outside access, keep it as hands-off and restricted as possible. For example, using a Telegram bot. Also keep it as minimal as possible, e.g. Don't expose the Editor - EVER! If you want to provide remote control of your heating or the precious plants in your greenhouse, provide explicit controls with strong limits. Don't expose ever…

You state the devices don't have a fixed ip, do you have any control over the devices? What are they?

Which is perfectly possible - but dangerous if you don't know what you are doing.
