Choose the firewall zone you want to assign to this interface. Select unspecified to remove the interface from the associated zone or fill out the create field to define a new zone and attach the interface to it

Creates a bridge over specified interface(s)

Enables the Spanning Tree Protocol on this bridge

Physical interface name to assign to this section, list of interfaces if type bridge is set

Physical interface name to assign to this section, list of interfaces if type bridge is set

Protocol to use for this interface

Your router’s address on the network

Netmask defines how "large" a network is

The address where the router will send all the outgoing traffic

IP broadcasts are used by BOOTP and DHCP clients to find and send requests to their respective servers

Set interface properties regardless of the link carrier (If set, carrier sense events do not invoke hotplug handlers)

Override MAC address of the interface. For example, your ISP (Internet Service Provider) gives you a static IP address and it might also bind it to your computers MAC address (i.e., that IP will only work with your computer but not with your router). In this field you can select your computer’s MAC address and fool the gateway in to thinking that it is communicating with your computer. You can select the MAC address of a currently connected computer, or use a custom one. When changing MAC address on LAN interface be careful to avoid MAC address collisions

Maximum Transmission Unit (MTU) – specifies the largest possible size of a data packet

The configuration by default generates a routing table entry. In this field you can alter the metric of that entry. Lower metric means higher priority

Assign a part of given length of every public IPv6-prefix to this interface

Assign prefix parts using this hexadecimal subprefix ID for this interface

Assigns an IPv6 address for this interface. CIDR notation: address/prefix

IPv6 default gateway

Public prefix routed to this device for distribution to clients

Optional. Allowed values: 'eui64', 'random', fixed value like '::1' or '::1:2'. When IPv6 prefix (like 'a:b:c:d::') is received from a delegating server, use the suffix (like '::1') to form the IPv6 address ('a:b:c:d::1') for the interface
