[Linux] Zone Transfers

[Dean Benson]

    The company master is located behind the firewall and will be going
through the f/w to get the updates from the internet.  The "children" are
all internal DNS servers and will transfer from the master DNS server, never
going horrible and dangerous outside internet :o)  We just have way too many
users (many thousands!) all coming into our Baltimore office for DHCP and
DNS .. if you can believe it.  I know that TCP/IP traffic is light for this
type of traffic but our WAN links go down on occassion and it often kills
all work in the remote sites for TCP/IP based apps on each seperate LAN ...
