devstack: How can I use exiting public network on single node setup with Neutron

I am using devstack on single node with Neutron as networking service. I have 2 interfaces, eth0 and eth1. eth0 is my HOST_IP where I would like all the services to be running. eth1 is connected to public network and I have a pool of IP address from the public network which I want to use in external network creation. I see that the external network is created by devstack and takes values from FLOATING_RANGE and PUBLIC_NETWORK_GATEWAY. I want to: a. Specify pool range for this network. b. br-ex to be attached to eth1 so that it can connect to external network. c. The router created should pick-up starting IP address from the pool range instead of .1

I don't see any way to specify these in local.conf file. What is the best way to achieve this without creating an external network again?
