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
The RIP Version field controls the format and the broadcasting
method of the RIP packets that the device sends (it recognizes both
formats when receiving). RIP-1 is universally supported but RIP-2
carries more information. RIP-1 is probably adequate for most
networks, unless you have an unusual network topology. Both RIP-2B
and RIP-2M sends the routing data in RIP-2 format; the difference
being that RIP-2B uses subnet broadcasting while RIP-2M uses
multicasting. Multicasting can reduce the load on non-router machines
since they generally do not listen to the RIP multicast address and so
will not receive the RIP packets. However, if one router uses
multicasting, then all routers on your network must use multicasting,
also. By default, RIP direction is set to Both and the Version set to
RIP-1.
Select IGMP V-1 or 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 inter operability between IGMP
version 2 and version 1, please see sections 4 and 5 of RFC 2236.
Select this to allow traffic only from devices on the LAN which have
received an IP address from the selected device. This is done by
allowing traffic only from devices on the LAN with specific
combinations of IP and MAC addresses. These IP addresses are
dynamically assigned by the the selected device or manually set using
static DHCP.
Click static IP to go to the Device Configuration > Network > LAN
> Static DHCP screen for a list of static IP/MAC address combinations.
Set the selected device to allow packets from the LAN with source IP
addresses within a specified range. This allows packets even when
their IP and MAC addresses do not match those specified in the Device
Configuration > Network > LAN > Static DHCP screen.
Type this range of IP addresses in the From and To fields.
Select this check box to forward NetBIOS packets from the LAN to
WAN port 1and from WAN port 1 to the LAN. If your firewall is enabled
with the default policy set to block WAN port 1 to LAN traffic, you also
need to enable the default WAN port 1 to LAN firewall rule that
forwards NetBIOS traffic.
Clear this check box to block all NetBIOS packets going from the LAN
to WAN port 1 and from WAN port 1 to the LAN.
