Interface

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.

10.1.1What You Can Do in the Interface Screens

•Use the Status screen (Section 10.2 on page 202) to see all of the ZyWALL’s interfaces and their packet statistics.

•Use the Port Role screens (Section 10.3 on page 205) to set the ZyWALL’s flexible ports as lan1, ext-wlan or dmz.

•Use the Ethernet screens (Section 10.4 on page 206) 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 221) for PPPoE or PPTP Internet connections.

•Use the Cellular screens (Section 10.7 on page 226) to configure settings for interfaces for Internet connections through an installed 3G card.

•Use the WLAN screens (Section 10.9 on page 233) to configure settings for interfaces on a wireless LAN card.

•Use the VLAN screens (Section 10.12 on page 247) 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 10.13 on page 255) to combine two or more network segments into a single network.

•Use the Auxiliary screens (Section 10.14 on page 261) to configure the ZyWALL’s auxiliary interface to use an external modem.

•Use the Virtual Interface screen (Section 10.15 on page 263) 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 (Chapter 11 on page 269) to configure load balancing.
