How to disable userland-proxy on OSX?

Hi,
I am running a mysql DB in a docker container on OSx. It works fine except that all of the source addresses as seen by the database are mapped to the internal virtual ip of the docker container network. How can I change this behavior to ensure the source IPs are not NAT’d? Reading threads on this topic, I understand that setting userland-proxy to false should solve this problem. How do I change this setting on OSX?
