10.1 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.

10.1.1 What You Can Do in this Chapter

• Use the Port Role screen
and port groups to Ethernet interfaces.
• Use the Port Configuration screen
• Use the Ethernet screens
interfaces are the foundation for defining other interfaces and network policies. RIP and OSPF are also
configured in these interfaces.
• Use the Virtual Interface screen
Ethernet interfaces to tell the Zyxel Device where to route packets. You can create virtual Ethernet
interfaces, virtual VLAN interfaces, and virtual bridge interfaces.
• Use the PPP screens
• Use the Cellular screens
connections through an installed mobile broadband card.
• Use the Tunnel screens
Generic Routing Encapsulation (GRE), IPv6 in IPv4, and 6to4 tunnels.
• Use the VLAN screens
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
single network.
• Use the LAG screens
into a single logical interface.
• Use the VTI screens
interface according to the IP routing table.
• Use the Trunk screens
