Configure all the client machines behind the firewal to use z as their
nameserver.  Make z a master for subdomain.mydomain.com zone on z, but
don't mention it at all on y.  Configure z as a slave for mydomain.com.

Configure the firewall to allow z to send queries to the Internet.  Or
configure it to allow these queries only from z to x, and configure z to
use x as its forwarder.
