Here's my detailed description for my issue, please help.

Issue Description:
Quantum + OpenVswitch, and use devstack to do all-in-one installation. I
only add these lines into my localrc:
FIXED_RANGE=20.0.0.0/24
NETWORK_GATEWAY=20.0.0.1
FLOATING_RANGE=192.168.0.80/28

This is my trace record:

OpenStack running at 192.168.0.31
Create a new VM and it's fixed ip is 20.0.0.13
Ping an available physical host which ip is 192.168.0.30

OK: From 20.0.0.13 ping 192.168.0.30
FAILED: From 20.0.0.13 ping 192.168.0.31, no response.
