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.

NetBIOS over TCP/IP

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.
