This section introduces bridges and bridge interfaces and then explains the screens for bridge interfaces.
Bridge Overview

DESCRIPTION
Click Add to create an IPv4 Address, an IPv4 CIDR (for example, 192.168.1.1/24) or an IPv4
Range (for example, 192.168.1.2-192.168.1.100) as the target IP address. The Zyxel Device
answers external ARP requests only if they match one of these inputted target IP addresses.
For example, if the IPv4 Address is 192.168.1.5, then the Zyxel Device will answer ARP
requests coming from the WAN only if it contains 192.168.1.5 as the target IP address.
Select an existing entry and click Remove to delete that entry.
Click WAN TRUNK to go to a screen where you can set this VLAN to be part of a WAN trunk
for load balancing.
Click Policy Route to go to the screen where you can manually configure a policy route to
associate traffic with this VLAN.
Click OK to save your changes back to the Zyxel Device.
