Depending on what services you want to give access with, I have had great luck with an ultra cheap VPS

Then I host my edge services on a container and use an ssh tunnel to the remote host which gives me an ipv4 and any port forward that I want.

For example I have my reverse proxy inside my network and my VPN server then I use a command like:

ssh -R 8080:localhost:80 public.example.com

Which would forward publicip:8080 to localhost:80

I use autossh to keep the tunnel alive at all times.

This is an ultra cheap way to get any ports you want and self host the whole thing. The remote VPS also doesn’t get any extra access to your local network and doesn’t initiate the connection so it doesn’t have credentials for your local network

But if you don’t already have lifetime and are paying monthly or annually then that price is also almost doubling
