In that case, please refer to my previous e-mail : use floating IPs 
bound to the same physical network.
That's up to you to know which IP pools are available inside your 
network. Once you get one, create a external Quantum subnet defined with 
this IP range.

Sorry, I have feeling to explain again and again. If you still don't 
catch the point, could you please then tell me your physical net/CIDR, 
your free IP range and your gateway, and I'll mix you up the command to 
issue.
