CHAPTER 13 Interfaces 13.1 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. 13.1.1 What You Can Do in this Chapter • Use the Port Grouping screens (Section 13.2 on page 299) to create port groups and to assign physical ports and port groups to Ethernet interfaces. • Use the Ethernet screens (Section 13.3 on page 300) 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 13.4 on page 310) for PPPoE or PPTP Internet connections. • Use the Cellular screens (Section 13.5 on page 317) to configure settings for interfaces for Internet connections through an installed 3G card. • Use the WLAN screens (Section 13.6 on page 326) to configure settings for interfaces on a wireless LAN card. • Use the VLAN screens (Section 13.8 on page 341) 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 13.9 on page 351) to combine two or more network segments into a single network. • Use the Auxiliary screens (Section 13.10 on page 360) to configure the ZyWALL's auxiliary interface to use an external modem.
