On a FireBrick 2700 the DNS service defaults to local-only - this prevents access to the FireBrick DNS resolver from the WAN by default.

The setting for this is found in the Web config editor at:

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, e.g.:

DNS resolver access:-
This address is not on a local Ethernet subnet and so not allowed access.
