LABEL DESCRIPTION
RIP Version The RIP Version field controls the format and the broadcasting method of the RIP
packets that the HomeSafe sends (it recognizes both formats when receiving).
Choose RIP-1, RIP-2B or RIP-2M.
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, the RIP Version field is set to
RIP-1.
Multicast Choose None (default), IGMP-V1 or 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 and LAN 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.
Allow Trigger Dial Select this option to allow NetBIOS packets to initiate calls.
