HI all, Another day of failed attempts to get this right. Would appreciate any help you can give. Its been almost 3 weeks and I haven't been able to get past this point.

I have an All-in-one Devstack grizzly deployment here, but I cannot get the networking right no matter how I configure it.

My Physical Host NIC settings are:
auto eth0
iface eth0 inet static

#Secondary network not connected to anything(cable not plugged in)
auto eth1
        iface eth1 inet manual
        up ifconfig $IFACE up
        up ip link set $IFACE promisc on
        down ip link set $IFACE promisc off
        down ifconfig $IFACE down

What should my localrc file correctly look like? I really dont understand this. Should the floating IPs be on the same subnet as my host IP?
for example, HOST_IP= with the GW       FLOATING_RANGE=

if I dont configure any ips ranges then I always get a 172. IP for my public network and my instances do not get a IP from DHCP services.

Thank you for your help
