LABEL DESCRIPTION
RIP Direction RIP (Routing Information Protocol, RFC1058 and RFC 1389) allows a router to
exchange routing information with other routers. The
RIP Direction
field controls the
sending and receiving of RIP packets. Select the RIP direction from
Both
/
In
Only
/
Out Only
/
None
. When set to
Both
or
Out Only
, the ZyWALL will broadcast its
routing table periodically. When set to
Both
or
In Only
, it will incorporate the RIP
information that it receives; when set to
None
, it will not send any RIP packets and
will ignore any RIP packets received.
Both
is the default.
RIP Version The
RIP Version
field controls the format and the broadcasting method of the RIP
packets that the ZyWALL 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
.
Multicast 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 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 From LAN to
WAN
Select this option to forward NetBIOS packets from the LAN port to the WAN port.
Allow From LAN to
DMZ
Select this option to forward NetBIOS packets from the LAN port to the DMZ port.
(Not all ZyWALL models have a DMZ port.)
