10.1  Interface Overview
Use the Interface screens to configure the ZyWALL’s interfaces. You can also create 
interfaces on top of other interfaces. 
• Ports are the physical ports to which you connect cables.
• Interfaces are used within the system operationally. You use them in configuring various 
features. An interface also describes a network that is directly connected to the ZyWALL. 
For example, You connect the LAN1 network to the LAN1 interface. 
• Zones are groups of interfaces used to ease security policy configuration. 
10.1.1  What You Can Do in the Interface Screens
• Use the Status screen (
) to see all of the ZyWALL’s interfaces 
and their packet statistics.
• Use  the  Port Role screens (
) to set the ZyWALL’s flexible ports 
as lan1, ext-wlan or dmz. 
• Use  the  Ethernet screens (
Ethernet interfaces are the foundation for defining other interfaces and network policies. 
RIP and OSPF are also configured in these interfaces.
• Use the PPP screens (
) for PPPoE or PPTP Internet connections.
• Use the Cellular screens (
) to configure settings for interfaces 
for Internet connections through an installed 3G card.
• Use the WLAN screens (
) to configure settings for interfaces on 
a wireless LAN card.
• Use the VLAN screens (
) to divide the physical network into 
multiple logical networks. VLAN interfaces receive and send tagged frames. The 
ZyWALL automatically adds or removes the tags as needed. Each VLAN can only be 
associated with one Ethernet interface.
• Use the Bridge screens (
) to combine two or more network 
segments into a single network. 
• Use the Auxiliary screens (
) to configure the ZyWALL’s 
auxiliary interface to use an external modem.
• Use the Virtual Interface screen (
) to create virtual interfaces 
on top of Ethernet interfaces to tell the ZyWALL where to route packets.  You can create 
virtual Ethernet interfaces, virtual VLAN interfaces, and virtual bridge interfaces.
• Use  the Trunks screens (
) to configure load balancing.
