The more I am selfhosting the more ports I do open to my reverse proxy.
I also have a VPN (wireguard) but there are also 3 family members that want to access some services.
Open ports are much easier to handle for them.
How many users do you have and how many ports are open?
My case: 4 users (family)/ 8 reversed proxy ports
How many users and open ports have you?
A reverse proxy isn’t a substitute for a VPN for access outside your network. And it isn’t any less secure; you only need to open 1 port however all of your services will be accessible via that single port which is arguably less secure.
Everything that is managed by that RP, yes. One should obviously be careful when selecting what to expose.
