[rhos-list] floating IP not reachable

Hi,
I just installed a new all-in-one controller without quantum. Everything works fine and now I wan't to use floating IPs like described here: http://openstack.redhat.com/Floating_IP_range. I want to use my second NIC (em2) for this purpose. For the installation, I use my first NIC (em1) and packstack automatically created a bridge (br100).
I deleted the default network and created a new one, which is matching the subnet on which em2 is connected. After that I modified the public_interface in the nova.conf to em2 and also the floating_range with the subnet I just created. I didn't modify the flat_interface and let the default value (lo).
I just enabled the em2 interface but didn't assign any IP address to it.
I added two rules to the default group to allow ping and SSH.
I can start VMs and they got an internal IP address (from 192.168.32.0/22). I can also associate a floating IP to each VM. But I'm unable to ping a floating IP.
If someone has any idea to resolve the problem it would be very helpful.
And if someone has a configuration who runs correctly I would be interested how you configured your network interfaces and your nova.conf.
Thanks, Nicolas.
Here’s an output from my nova.conf :
public_interface=em2
default_floating_pool=nova
novncproxy_port=6080
dhcp_domain=novalocal
libvirt_type=kvm
floating_range=10.192.76.0/25
fixed_range=192.168.32.0/22
auto_assign_floating_ip=False
novncproxy_base_url=http://10.192.75.190:6080/vnc_auto.html
flat_interface=lo
vnc_enabled=True
flat_network_bridge=br100
