I changed

neutron subnet-create --name public_subnet --enable_dhcp=False --allocation_pool start=10.16.37.225,end=10.16.

37.254 --gateway=10.16.37.1 public 10.16.37.0/27

to

neutron subnet-create --name public_subnet --enable_dhcp=False --allocation_pool start=10.16.37.225,end=10.16.

37.254 --gateway=10.16.37.1 public 10.16.37.0/24

and successfully created.

But I'm still not able to ping to instance. I launched an instance using demo user. Defined custom TCP and custom ICMP rule in security policy.

Please help...

Hi Jason

I followed the link
http://community.redhat.com/blog/2015/01/rdo-quickstart-doing-the-neutron-dance/

And it struck at the command:
neutron subnet-create --name public_subnet --enable_dhcp=False --allocation_pool start=10.16.37.225,end=10.16.37.254 --gateway=10.16.37.1 public 10.16.37.0/27

Bad Request (HTTP 400) (Request-ID: req-668832aa-67a1-4b0d-ad6e-7a2c8aae905f)

Can you please guide me, what should I do next?

If the range from your external dhcp and the range for your floating IPs
overlap, you can end up w/ multiple machines getting the same IP.
