11.1 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.

11.1.1 What You Can Do in this Chapter

• Use the Port Role screens
and to assign physical ports and port groups to Ethernet interfaces.
• Use the Ethernet screens
interfaces. 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
connections.
• Use the Cellular screens
interfaces for Internet connections through an installed 3G card.
• Use the VLAN screens
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
network segments into a single network.
• Use the Virtual Interface screen
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 Trunk screens
