Chapter 10 Interfaces; Interface Overview; What You Can Do In This Chapter - ZyXEL Communications USG40 User Manual

10.1 Interface Overview

Use the Interface screens to configure the ZyWALL/USG'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/USG.
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
physical ports and port groups to Ethernet interfaces.
• Use the Ethernet screens
Ethernet 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
top of Ethernet interfaces to tell the ZyWALL/USG 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
Internet 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
logical networks. VLAN interfaces receive and send tagged frames. The ZyWALL/USG
automatically adds or removes the tags as needed. Each VLAN can only be associated with one
Ethernet interface.
• Use the Bridge screens
into a single network.
• Use the LAG screens
interfaces into a single logical interface.
• Use the VTI screens
interface according to the IP routing table.
• Use the Trunk screens
