You can specify the gateway_ip when creating the subnet: --gateway <IP ADDRESS> This should be the gateway that external network traffic should be routed to by default (probably your default outbound route for internet access). When you associate the external network with the router using 'quantum router-gateway-set' the quantum l3-agent will configure a router with an IP address on the quantum host using an IP from the allocation pool.
