Dear All,
We get a pool of Public IPs which statically map to private IP addresses .
If I assign any one of those private IP address to physical interface it is
reachable from internet.
In neutron setup I created the external network using the range of those
private ip addresses and associate them as Floating IPs to the instances .
When I ping/connect using the floating IPs (range from private IPs) it
works , but when I use the assigned public IP it cannot ping/connect.
*Our setup:*
internet -> public ip -> natted-private-ip ->neutron-internal-ip->instance
|

|
|
-- Natted (floating ips) --
*Typical setup:*
internet -> public ip -> neutron-internal-ip->instance
| |
| |
-- Natted (floating ips) --
Any hint ?
