Interfaces
9.1 Interface Overview
Use the
Interface
screens to configure the 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 USG. 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
) to create port groups and to assign physical
ports and port groups to Ethernet interfaces.
• Use the
Ethernet
screens (
) 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
) for PPPoE or PPTP Internet connections.
• Use the
Cellular
) to configure settings for interfaces for
Internet connections through an installed mobile broadband card.
• Use the
Tunnel
screens (
) to configure tunnel interfaces to be used in
Generic Routing Encapsulation (GRE), IPv6 in IPv4, and 6to4 tunnels.
• Use the
VLAN
screens (
) to divide the physical network into multiple
logical networks. VLAN interfaces receive and send tagged frames. The USG automatically adds
or removes the tags as needed. Each VLAN can only be associated with one Ethernet interface.
• Use the
Bridge
screens (
) to combine two or more network segments
into a single network.
• Use the
Auxiliary
screens (
) to configure the USG’s auxiliary interface to
use an external modem.
• Use the
Virtual Interface
screen (
) to create virtual interfaces on top
of Ethernet interfaces to tell the USG where to route packets. You can create virtual Ethernet
interfaces, virtual VLAN interfaces, and virtual bridge interfaces.
• Use the
Trunk
) to configure load balancing.
