I created a network/subnet/router tuple in a DVR setup (slight chance I 
added --distributed false to the router-create - I've reinstalled the 
setup at this point so cannot check), noted the public IP of the router, 
and the private IP of the instance, then on one of my controllers which 
was connected to the external VM VLAN on which the router is I added a 
host route for the instance's private IP, pointing at the public IP of 
the router and started pinging.  The neutron private network was VxLAN, 
and in my case carried on a separate VLAN from the External VM VLAN.  In 
my case, the instances private IP was a 192.168.123.X, and the router's 
public IP was a 10.249.mutter.

I didn't try anything from farther afield because I don't have control 
of those bits in my particular test environment.

happy benchmarking,
