Hi, I need to have some answer of my doubts before i fully migrate to a odoo server :

1) Can we have a website based on a PHP/HTML sources files linked to a postgres database on a odoo server. This looks fine with the "Siteweb" module and a nice tutoriel.

2) My main concern is that I have to send data to a private IP, so I need to have a openVPN installed on my webserver, Is that doable ? Do I need a addon or can I directly implement it on my server ?

I already setup an odoo (version 16) server, but I want to know if all this is possible before i investigate further.

Thank you.
