CHAPTER 9 Interfaces 9.1 Interface Overview Use the Interface screens to configure the Zyxel Device'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 Zyxel Device. For example, You connect the LAN network to the LAN interface. • Zones are groups of interfaces used to ease security policy configuration. 9.1.1 What You Can Do in this Chapter • Use the Port Role screen (Section 9.2 on page 243) to create port groups and to assign physical ports and port groups to Ethernet interfaces. • Use the Port Configuration screen (Section 9.3 on page 244) to configure Zyxel Device port settings. • Use the Ethernet screens (Section 9.4 on page 245) 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 9.5 on page 268) for PPPoE, PPTP or L2TP Internet connections. • Use the Cellular screens (Section 9.6 on page 275) to configure settings for interfaces for Internet connections through an installed mobile broadband card. • Use the Tunnel screens (Section 9.7 on page 284) to configure tunnel interfaces to be used in Generic Routing Encapsulation (GRE), IPv6 in IPv4, and 6to4 tunnels. • Use the VLAN screens (Section 9.8 on page 291) to divide the physical network into multiple logical networks. VLAN interfaces receive and send tagged frames. The Zyxel Device automatically adds or removes the tags as needed. Each VLAN can only be associated with one Ethernet interface. • Use the Bridge screens (Section 9.9 on page 304) to combine two or more network segments into a single network. • Use the VTI screens (Section 9.10 on page 318) to encrypt or decrypt IPv4 traffic from or to the interface according to the IP routing table. • Use the Trunk screens (Section 9.11 on page 323) to configure load balancing. 9.1.2 What You Need to Know Interface Characteristics Interfaces generally have the following characteristics (although not all characteristics apply to each type of interface).
