Multicast

Select which version of IGMP the ZyXEL Device uses to support multicasting on 
the LAN. 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).

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.

Allow between 
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.

Cancel

Click this to set every field in this screen to its last-saved value.
