The setting for this is found

Config -> Edit -> Setup -> General system services -> DNS service settings -> local-only

Testing Access

The web interface of the FireBrick can list what services are open, go to

Diagnostics -> Access Check

Enter an Source IP of an IP on the Internet.

The FireBrick will then list all the services open to that IP address, eg:

This address is not on a local Ethernet subnet and so not allowed access.
