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?
Depending on the services you provide, the usual standard ports. So if you run http/https services, port 80 and 443 respectively.
You seem to answer your own question.
