Configuration
This feature is not applicable/available when you configure the ZyXEL Device to
use a static WAN IP address or in bridge mode.
Select Yes to set the ZyXEL Device to automatically detect the Internet
connection settings (such as the VCI/VPI numbers and the encapsulation method)
from the ISP and make the necessary configuration changes.
Select No to disable this feature. You must manually configure the ZyXEL Device
for Internet access.
PPPoE
Passthrough
(PPPoE
encapsulation
only)
This field is available when you select PPPoE encapsulation.
In addition to the ZyXEL Device's built-in PPPoE client, you can enable PPPoE pass
through to allow up to ten hosts on the LAN to use PPPoE client software on their
computers to connect to the ISP via the ZyXEL Device. Each host can have a
separate account and a public WAN IP address.
PPPoE pass through is an alternative to NAT for application where NAT is not
appropriate.
Disable PPPoE pass through if you do not need to allow hosts on the LAN to use
PPPoE client software on their computers to connect to the ISP.
