so I figured in order to access 10.0.16.103 the deployment had to be made inside the same subnet as CF. I changed the networks/cloud_properties/subnet to cf_private subnet_ID and it worked.

Now I'm getting "`gateways/0' is not running after update" but I suppose it's a totally different issue (ref: http://grokbase.com/t/cloudfoundry.org/bosh-users/12cwqa2php/error-400007-%60mysql-gateway-0-is-not-running-after-update )
