Interface Properties
Interface Type This field is configurable for the OPT interface only. Select to which type of network
you will connect this interface. When you select internal or external the rest of the
screen’s options automatically adjust to correspond. The USG automatically adds
default route and SNAT settings for traffic it routes from internal interfaces to external
interfaces; for example LAN to WAN traffic.
internal is for connecting to a local network. Other corresponding configuration
options: DHCP server and DHCP relay. The USG automatically adds default SNAT
settings for traffic flowing from this interface to an external interface.
external is for connecting to an external network (like the Internet). The USG
automatically adds this interface to the default WAN trunk.
For general , the rest of the screen’s options do not automatically adjust and you must
manually configure a policy route to add routing and SNAT settings for the interface.
Interface Name Specify a name for the interface. It can use alphanumeric characters, hyphens, and
underscores, and it can be up to 11 characters long.
Port This is the name of the Ethernet interface’s physical port.
Zone Select the zone to which this interface is to belong. You use zones to apply security
settings such as security policy, and remote management.
MAC Address This field is read-only. This is the MAC address that the Ethernet interface uses.
Description Enter a description of this interface. It is not used elsewhere. You can use
alphanumeric and
()+/:=?!*#@$_%-
characters, and it can be up to 60 characters
long.
IP Address
Assignment These IP address fields configure an IPv4 IP address on the interface itself. If you
change this IP address on the interface, you may also need to change a related
address object for the network connected to the interface. For example, if you use this
screen to change the IP address of your LAN interface, you should also change the
corresponding LAN subnet address object.

indicates what part of the IP address is the same for all computers in the network.
