Frames Between
WAN and Local
Ports
Select this option to forward PPPoE packets from the WAN port to the
LAN ports and from the LAN ports to the WAN port.
In addition to the Device's built-in PPPoE client, you can select this to
allow up to ten hosts on the LAN to use PPPoE client software on their
computers to connect to the ISP via the Device. Each host can have a
separate account and a public WAN IP address.
This is an alternative to NAT for application where NAT is not
appropriate.
Clear this if you do not need to allow hosts on the LAN to use PPPoE
client software on their computers to connect to the ISP.
This field is not available for a PPPoA connection.
Enable IGMP
Multicast Proxy
Select this check box to have the Device act as an IGMP proxy on this
