[Openstack-operators] How to define transparent proxy in Neutron

Well, it's bit complicated. Because 'proxy' usually working on L5+ 
(http,https, ftp,etc). And instances wants pure L3 functionality. For 
example, how you expects to 'proxy' NFS connection from instance to 
white IP outside your networking? Even if you not plan to do this, 
architecture expects to be capable to.

Theoretically you can intercept http/ftp/https traffic on router and 
push it to the transparent proxy (google it!). I think this can be done 
even on neutron-l3-agent host, but it better to disable network 
namespaces and add some hacks to iptables 'for all tenants'.
