Packet filtering
By default, one preconfigured packet filtering rule, Allow all outgoing traffic, is enabled and
monitors traffic going to and from the Connect EZ device. The predefined settings are intended to
block unauthorized inbound traffic while providing an unrestricted flow of outgoing data. You can
modify the default packet filtering rule and create additional rules to define how the device accepts or
rejects traffic that is forwarded through the device.
