interface (ZONE)
The physical Ethernet ports are shown at the top and the Ethernet interfaces and zones are shown
at the bottom of the screen. Use the radio buttons to select for which interface (network) you want
to use each physical port. For example, select a port's LAN radio button to use the port as part of
the LAN interface. The port will use the ZyWALL/USG's LAN IP address and MAC address.
When you assign more than one physical port to a network, you create a port group. Port groups
have the following characteristics:
• There is a layer-2 Ethernet switch between physical ports in the port group. This provides wire-
speed throughput but no security.
• It can increase the bandwidth between the port group and other interfaces.
• The port group uses a single MAC address.
Click Apply to save your changes and apply them to the ZyWALL/USG.
Click Reset to change the port groups to their current configuration (last-saved values).

8.3 Ethernet Summary Screen

This screen lists every Ethernet interface and virtual interface created on top of Ethernet interfaces.
If you enabled IPv6 in the Configuration > System > IPv6 screen, you can also configure
Ethernet interfaces used for your IPv6 networks on this screen. To access this screen, click
Configuration > Network > Interface > Ethernet.
Unlike other types of interfaces, you cannot create new Ethernet interfaces nor can you delete any
of them. If an Ethernet interface does not have any physical ports assigned to it, the Ethernet
interface is effectively removed from the ZyWALL/USG, but you can still configure it.
Ethernet interfaces are similar to other types of interfaces in many ways. They have an IP address,
subnet mask, and gateway used to make routing decisions. They restrict the amount of bandwidth
and packet size. They can provide DHCP services, and they can verify the gateway is available.
Use Ethernet interfaces to control which physical ports exchange routing information with other
routers and how much information is exchanged through each one. The more routing information is
