It appears that the SSG series can perform DNS lookups, but doing so only using forwarders and not root hints.

See screenshot below... these are ALL the configuration options available.

@alex you can configure per domain dns forwarding and/or a catchall option, yo to Network > DNS > Proxy and mark: "Initialize Proxy DNS Server" and "Enable Proxy DNS Server", click on Apply.

Then click in New and add the domain name that you want to forward (use * to forward all requests), configure the primary, secondary and tertiary DNS IP Address. Optionally select the Interface when all this request will get out.

Then, you need to go to Network > Interfaces Edit the interface where you want to set the dns proxy, mark DNS Proxy option, and that's it!, you got it.

On the cli you can type (:

set dns proxy
set dns proxy enable
set dns server-select domain * primary-server x.x.x.x secondary-server y.y.y.y tertiary-server z.z.z.z
set interface ethernet#/# proxy dns
