2. Configure interfaces as shown on figure:

   

3. Set a gateway for the private network:

   1. Login with ssh to Fuel master node.

   2. List existing network-groups:

      fuel network-group --env 1
      

   3. Remove and create again network-group private to set a gateway:

      fuel network-group --delete --network 5
      fuel network-group --create --name private \
      --cidr 10.109.3.0/24 --gateway 10.109.3.1 --nodegroup 1
      

4. Set the render_addr_mask parameter to internal for this network by typing:

   fuel network-group --set --network 6 \
   --meta '{"name": "private", "notation": "cidr",\
     "render_type": null, "map_priority": 2, \
     "configurable": true, "use_gateway": true,\
     "render_addr_mask": "internal", "vlan_start": null, \
     "cidr": "10.109.3.0/24"}'
   

5. Save sample network template

6. Upload the network template by typing:
