DNS and SQUID - Question from Newbie

[Robert E. Daumann]

Hi
i  have an internal network with 10 Clients (diffrent OS). The server is
al Linux machine.  The clients get their IP from a DHCP-Server.
On the internal net are sensitive files, so i have to protect them
against attacks from outside. With the linux server I make the contact
to
the Internet.
To protect the system I install SQUID, but squid won't run, cause at
boot time he looks for a nameserver. The  first choice is, putting the
outside nameserverlist at the resolv.conf. But during boot, linux server
make a connect to the Internet. Now I want't to run my own DNS with BIND
8.
The question is, do I need a master.zone or a slave.zone, or a master
and a slave, or a slave an a forward??

please help me

Robert
