Interfaces
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 LAN network
to the ge1 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 ( Section 10.2 on page 173 ) to see all of the ZyWALL’s
interfaces and their packet statistics.
• Use the Port Grouping screens ( Section 10.3 on page 176 ) to create port
groups and to assign physical ports and port groups to Ethernet interfaces.
• Use the Ethernet screens ( Section 10.4 on page 177 ) to configure the Ethernet
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 ( Section 10.6 on page 186 ) for PPPoE or PPTP Internet
connections.
• Use the Cellular screens ( Section 10.7 on page 192 ) to configure settings for
interfaces for Internet connections through an installed 3G card.
• Use the VLAN screens ( Section 10.9 on page 201 ) 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 ( Section 10.10 on page 209 ) to combine two or more
network segments into a single network.
• Use the Auxiliary screens ( Section 10.11 on page 216 ) to configure the
ZyWALL’s auxiliary interface to use an external modem.
