Multicast

Choose None (default), IGMP-V1or IGMP-V2. 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.

 

 

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.

 

 

Allow between WAN

Select this check box to forward NetBIOS packets from the LAN to the WAN

 

 

and LAN

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.

 

 

Allow Trigger Dial

Select this option to allow NetBIOS packets to initiate calls.
