Stopping Open DNS - FireBrick 2700

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

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:

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