" PREQUISITES or WHERE USED does not appear if there are no
prerequisites or references in other features to this one. For example, no other
features reference DDNS entries, so there is no WHERE USED entry.
5.4.2 Interface
See Section 5.2 on page 110 for background information.
" When you create an interface, there is no security applied on it until you assign
it to a zone.
Most of the features that use interfaces support Ethernet, PPPoE/PPTP, cellular, wireless
LAN, VLAN, and bridge interfaces.
Example: The dmz interface is in the DMZ zone and uses a private IP address. To configure
dmz’s settings, click Network > Interface > Ethernet and then the dmz’s Edit icon.
5.4.3 Trunks
Use trunks to set up load balancing using two or more interfaces.
Example: See Chapter 6 on page 125.
5.4.4 IPSec VPN
Use IPSec VPN to provide secure communication between two sites over the Internet or any
insecure network that uses TCP/IP for communication. The ZyWALL also offers hub-and-
spoke VPN.
