First step would be to ensure that you can do port forwarding.
Check if your IP address isn’t a private one or CGNAT.
Now set up reverse proxy and try connecting to your service. If it connects, you are okay.
Now this is something i didn’t know could happen but it did end up happening to me. I was happily port forwarding for a few months, until suddenly my port forwarding stopped working. Now I called my ISP, they said they did nothing(my ISP is a few guys who have no Idea about what they are doing, the other option to them is 512kbps DSL connection) at this point all my ingress ports are blocked and even outgoing ssh is blocked. Then the new month starts and everything is working again. I looked at my ISP website to get an idea of what may have caused this and the case seems to be that it was the first time I crossed 100GB in uploading. So my ISP has configured things such a way that port forwarding only works for the first 100GB of uploading.
This is why I strongly recommend cloudfare tunnel or any other similar solution.
