DESCRIPTION
Multicast packets are sent to a group of computers on the LAN and are an
alternative to unicast packets (packets sent to one computer) and broadcast
packets (packets sent to every computer).
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a multicast group.
version 1 and version 2. Select Enable to turn on IGMP. Otherwise, select Disable.
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.
This section is not available when you configure the ZyXEL Device to be in bridge
mode.
Select this option to enable IP filtering on this connection.
Select this option to enable VLAN multiplexing of multiple protocols over a single
virtual circuit. You need to assign a VLAN ID and priority level to traffic through
each WAN connection. All WAN connections share one MAC address. This allows
the backbone switch to classify and service traffic based on the VLAN tag.
Otherwise, disable VLAN multiplexing and each WAN connection has its own MAC
address.
Note: This field is only configurable for the first WAN connection.
When you change the setting here, all existing WAN
connections will be removed except for the first WAN
connection.
Enter a VLAN ID number for traffic that goes through this connection.
Enter a priority level for traffic that goes through this connection.
