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. 

Use trunks to set up load balancing using two or more interfaces.

Example: See 

.

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.
