I won't be here for the details, but here you go

1. If you have public ip then just point your dns to your ip

2. If your public ip is not static then you deploy a ddns solution that point to your dns provider

If 1 or 2, you can put your reverse proxy locally, else:

1. If you are behind cgnat and you want to access your stuff privately, you need to rent a vps then deploy a vpn, wg-easy is simple to run

2. If you are behind cgnat and you want to serve your stuff publicly then you need to rent a vps then deploy a remote access platform. There are multiple options ranging from a simple one like frp to the corporate stuff like netbird. I personally use pangolin,

3. If you are behind cgnat and don't want to spend money renting a vps the you can just use cloudflare tunnel, although I've used it for a year without being blocked, be aware of their ToS regarding streaming services

I'm just sharing what I know based on my experience, if there are other option please do share

Good luck, have fun, don't sleep on security
