Using ACLs
Use this window to define ACLs (access control lists) to enforce access restrictions.
After providing a distinct name under Name, specify an IP address (with or without
netmask) under Value in the following fashion:
{ 10.10/16; }
The syntax of the configuration file requires that the address ends with a semicolon and
is put into curly braces.
TSIG Keys
The main purpose of TSIGs (transaction signatures) is to secure communications between
DHCP and DNS servers. They are described in Section 33.7, "Secure Transactions"
(page 631).
To generate a TSIG key, enter a distinctive name in the field labeled Key ID and specify
the file where the key should be stored (Filename). Confirm your choices with Add.
To use a previously created key, leave the Key ID field blank and select the file where
it is stored under File Name. After that, confirm with Add.
Adding a Slave Zone
To add a slave zone, select DNS Zones, choose the zone type Slave, and click Add.
In the Zone Editor under Master DNS Server IP, specify the master from which the
slave should fetch its data. To limit access to the server, select one of the ACLs from
the list. See Figure 33.5, "DNS Server: Slave Zone Editor" (page 616).
