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 Prestige 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.

information that it receives; when set to None, it will not send any RIP packets and

RIP Version The RIP Version field controls the format and the broadcasting method of the RIP
packets that the Prestige 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.

Any IP Setup
Active Select this option to activate the Any-IP feature. This allows a computer to access
the Internet without changing the network settings (such as IP address and subnet
mask) of the computer, even when the IP addresses of the computer and the
Prestige are not in the same subnet.
When you disable the Any-IP feature, only computers with dynamic IP addresses or
static IP addresses in the same subnet as the Prestige’s LAN IP address can
connect to the Prestige or access the Internet through the Prestige.

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.
