Kumar, check these two articles to see if they help at all: <http://blog.scottlowe.org/2014/05/01/an-introduction-to-openstack-heat/> <http://blog.scottlowe.org/2014/05/02/another-look-at-an-openstack-heat-template/> If I'm correctly reading the sample template you're using, it looks like you should just need to create a Neutron port on each network (referencing the network's ID when creating it) and then reference those ports when creating the instance. Also, refer to Clint Byrum's reply to you dated 08 Aug 2014, in which he mentioned adding this text to the properties section (I'm assuming he means the properties section of the web server): properties: networks: - { network: public } - { network: private } I hope this helps.
