CHAPTER 11 Interfaces 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 (Section 11.2 on page 218) to create port groups and to assign physical ports and port groups to Ethernet interfaces. • Use the Ethernet screens (Section 11.3 on page 219) 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 11.4 on page 231) for PPPoE or PPTP Internet connections. • Use the Cellular screens (Section 11.5 on page 237) to configure settings for interfaces for Internet connections through an installed 3G card. • Use the VLAN screens (Section 11.6 on page 246) 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 11.7 on page 256) to combine two or more network segments into a single network. • Use the Virtual Interface screen (Section 11.7.3 on page 264) 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 Trunk screens (Chapter 12 on page 271) to configure load balancing.
