My environment:

                    public ip                  internal ip(br100)
    netmask                gateway
controller:   10.11.3.62                 10.200.200.2
 255.255.255.0        10.11.3.1

node:         10.11.3.63                 10.200.200.3
 255.255.255.0        10.11.3.1

I used FLATDHCP to create a network is:  10.200.200.0/24  gateway
10.200.200.1
floating ip range: 10.11.3.201-10.11.3.210

Now I create a instance:

ip:10.200.200.51
floating:10.11.3.201
*********************************************

Do something:

*instance: ping www.google.com is ok, can visit internet*.
*traceroute to www.google.com* (72.14.203.99), 30 hops max, 40 byte packets
1 10.200.200.2 (10.200.200.2) 0.215 ms 0.272 ms 0.274 ms
2 10.11.3.253 (10.11.3.253) 0.861 ms 1.663 ms 1.931 ms
........(omission)
22 tx-in-f99.1e100.net (72.14.203.99) 209.880 ms 207.110 ms 208.317 ms

what's 10.11.3.253? I have no this ip to set it gateway.

*host: can not visit internet.why? when I install openstack via git, I used
internet no problem. But now, I cannot.*
Then I traceroute my gateway 10.11.3.1
traceroute to 10.11.3.1 (10.11.3.1), 30 hops max, 60 byte packets
1 10.11.3.253 (10.11.3.253) 0.686 ms * *

why need through 10.11.3.253?

I want to know how the data send?
