Yunohost servers offline network

Hi

I was wondering if its possible to have many Yunohost servers interconnected with each other without internet in a small area or community?

Or

Is there a way that Yunohost servers can be connected through one dedicated VPN which is closed for the normal internet ?

Hi, what do you mean by interconnected? As a cluster with common database of users and apps?

If it is just to make them see each other, then VPN is fine, or even some standard network if they are in a same building. You need to modify the /etc/host file to associate their internal IPs to hostnames on each device wanting to access it though.
I don’t think YunoHost needs internet. You can install applications from local storage.

Did you have any specific idea of use in mind?
