| 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. |
|
| |
|
| |
|
| 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 | Select this check box if you want the ZyXEL Device to send NetBIOS (Network |
| LAN and WAN | 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. |
