Multicast Setup
Multicast
Windows Networking (NetBIOS over TCP/IP): NetBIOS (Network Basic Input/Output System) are TCP
or UDP broadcast packets that enable a computer to connect to and communicate with a LAN. For
some dial-up services such as PPPoE or PPTP, NetBIOS packets cause unwanted calls. However it
may sometimes be necessary to allow NetBIOS packets to pass through to the WAN in order to find a
computer on the WAN.

DESCRIPTION
Select IGMP V-1, IGMP V-2 or None. IGMP (Internet Group Multicast
Protocol) is a network-layer protocol used to establish membership in a
Multicast group - it is not used to carry user data. IGMP version 2 (RFC 2236)
is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in
wide use. If you would like to read more detailed information about
interoperability between IGMP version 2 and version 1, please see sections 4
and 5 of RFC 2236.
Select this check box to forward NetBIOS packets from the LAN to the WAN
and from the WAN to the LAN. If your firewall is enabled with the default
policy set to block WAN to LAN traffic, you also need to enable the default
WAN to LAN firewall rule that forwards NetBIOS traffic.
Clear this check box to block all NetBIOS packets going from the LAN to the
WAN and from the WAN to the LAN.
Select this option to allow NetBIOS packets to initiate calls.
