Re: Network Connectivity issue


Hi Nicolas, thanks for using our distro!

Just to summarize:
- Single node
- Management network: = to
Let's assume gateway =
- Service Network: = to
gateway should be =

If you wan to ping from the service network to a host in the management
network (and it's not the single node) you need a route to that network. Or
you can configure your system to use the Management Network as the public
network. Then you will reach your hosts.

If you are using FlatDHCP, may be you can configure the smart installer to
use as the service network a subset (not a subnet) of the management
network. It's a dirty hack (I prefer to split networks always) we did in
the past...

For example if you want to setup a little lab in your lapto with the distro
you can use this settings:
- Single node
- Management network: (this is my network, use yours)
- Service Network:
- Public Network (floating range): (and of course I don't
have any host in this subnet)

With this configuration floating IPs will reach hosts in the management
