Multicast Select which version of IGMP the ZyXEL Device uses to support multicasting on
the WAN. Multicasting sends packets to some computers on the WAN and is an
alternative to unicasting (sending packets to one computer) and broadcasting
(sending packets to every computer).
None - The ZyXEL Device does not support multicasting.
IGMP-v1 - The ZyXEL Device supports IGMP version 1.
IGMP-v2 - The ZyXEL Device supports IGMP version 2.
Multicasting can improve overall network performance. However, it requires extra
processing and generates more network traffic. In addition, other computers on
the WAN have to support the same version of IGMP.

LAN and WAN
Select this check box if you want the ZyXEL Device to send NetBIOS (Network
Basic Input/Output System) packets between the LAN and WAN. You should also
make sure that NetBIOS packets are not blocked in Security > Firewall >
Services.
NetBIOS packets are TCP or UDP packets that enable a computer to connect to
and communicate with computers on other networks. It may sometimes be
necessary to allow NetBIOS packets to pass through the ZyXEL Device in order to
allow computers on the LAN to find computers on the WAN and vice versa.
This is the same setting you can set in Network > LAN > Advanced.
Allow Trigger Dial Select this if you want to allow NetBIOS packets to initiate calls.
Apply Click this to save your changes and to apply them to the ZyXEL Device.
