First i have created external network, router and security group using following command quantum net-create public --router:external=True Then i added my external network subnet (ip pool not used in external network) Then i created router Then i set my router gateway to external network I created security group to allow ssh and icmp. On second step i created private network with dhcp enabled Then created router interface and attach it to my private network (HowTos)
