Dear OpenStackers,

I started my 2nd try installing OpenStack single node guided using this link:

At the point sunbeam cluster bootstrap I have to decide network settings:

sudo sunbeam cluster bootstrap

Management networks shared by hosts (CIDRs, separated by comma) (192.168.196.0/24):

The example given is this:

Unfortunately there is no information about the LAN the server is running in.

What does "Management networks shared by hosts“ mean?

I have ONE host (OpenStack)

What should be shared? To whom ?

I do not understand the clue behind that.

The MetalLB addresses are for the VMs, right?

So they must be in an address range of my LAN

During my first installation (also single node, but not guided) I was not asked for different networks. 

Finally I was unable to reach Horizon from my LAN. 

I tried many efforts with routing (nft), but I did not work. 

Everything seemed live inside my host, but unusable, because I am running Ubuntu Server 24.02 in a Rack using ssh - so: no GUI.

I hoped to get another chance with this „guided" installation. 

1. A dedicated network inside OpenStack where all components are communicating with each other without interfering with my LAN.

2. Access to the Dashboard (Horizon) from my LAN

3. Access to VMs I am using inside OpenStack from my LAN

Because I am working over ssh, the host uses an IP number from my LAN (192.168.196.11)

There are about 20 IPs free in my LAN

The question "Management networks shared by hosts (CIDRs, separated by comma) (192.168.196.0/24):“ shows the whole network (/24) as given.
