11.0 Network Tab
You can view and configure the interfaces of the local area network (LAN) zone as well as the wide
area network (WAN) zone. Network address translation (NAT) occurs between these two network
zones. The router that performs the NAT is called a gateway. A gateway is a network point that
acts as an entrance to another network.
Figure 32: The Network top-level tab.
Figure 33: The Interface Overview on the Network » Interfaces page.
The Network column shows that the WAN zone has the physical port “eth1” as its interface.
In Figure 33, the LAN zone (icon with two Ethernet ports) has the bridged interface “br-lan” which
consists of one physical port (icon with one Ethernet port) and two wireless networks (each icon
looking like a short standing fan) on the device. Hovering the mouse over each icon would give
the name of the interface it represents.
