LABEL	DESCRIPTION
Enable SUA	Network Address Translation (NAT) allows the translation of an Internet protocol
	address used within one network to a different IP address known within another
	network.
	SUA (Single User Account) is a subset of NAT that supports two types of
	mapping: Many-to-One and Server. When you select this option the Prestige will
	use Address Mapping Set 255 in the SMT (see the section on menu 15.1 for
	more information).
Enable RIP	Select this check box to turn on RIP (Routing Information Protocol), which allows
	a router to exchange routing information with other routers.
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).
	Choose RIP-1,RIP-2B or RIP-2M.
	RIP-1is universally supported; but RIP-2carries more information. RIP-1 is
	probably adequate for most networks, unless you have an unusual network
	topology. Both RIP-2Band RIP-2Msends 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.
RIP Direction	RIP (Routing Information Protocol) allows a router to exchange routing
	information with other routers. The RIP Direction field controls the sending and
	receiving of RIP packets.
	Choose Both, In Only or Out Only.
	When set to Both or Out Only, the Prestige will broadcast its routing table
	periodically.
	When set to Both or In Only, the Prestige will incorporate RIP information that it
	receives.
Enable Multicast	Select this check box to turn on IGMP (Internet Group Multicast Protocol). IGMP
	is a network-layer protocol used to establish membership in a Multicast group - it
	is not used to carry user data.
Multicast	Select IGMP-v1or IGMP-v2. 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.
