Open Stack

Yeah I saw that mistake so i change my subnet to192.168.100.0/24 which should be able to communicate now.

But I still have the same problem. 

Could it be a problem with br-ex or br-int? 

On the network topology view the gateway for the public network still does not display properly. Like it is missing.

Thanks again

That means, machines in range 192.168.100.96 to 192.168.100.127 would be able to communicate among each other. 192.168.100.1/24 or 192.168.100.1/27 won't be able to communicate with the public-ip address range(192.168.100.96/27) which you have specified because of subnetting.
