	HomeSafe User’s Guide
	Table 5-1 LAN : IP
LABEL	DESCRIPTION
First DNS Server	Select From ISP if your ISP dynamically assigns DNS server information (and the
Second DNS	HomeSafe's WAN IP address). The field to the right displays the (read-only) DNS
Server	server IP address that the ISP assigns.
Third DNS Server	Select User-Definedif you have the IP address of a DNS server. Enter the DNS
	server's IP address in the field to the right. If you chose User-Defined, but leave
	the IP address set to 0.0.0.0, User-Definedchanges to None after you click
	Apply. If you set a second choice to User-Defined, and enter the same IP
	address, the second User-Definedchanges to None after you click Apply.
	Select DNS Relay to have the HomeSafe act as a DNS proxy. The HomeSafe's
	LAN IP address displays in the field to the right (read-only). The HomeSafe tells the
	DHCP clients on the LAN that the HomeSafe itself is the DNS server. When a
	computer on the LAN sends a DNS query to the HomeSafe, the HomeSafe
	forwards the query to the HomeSafe's system DNS server (configured in the
	SYSTEM General screen) and relays the response back to the computer. You can
	only select DNS Relay for one of the three servers; if you select DNS Relay for a
	second or third DNS server, that choice changes to None after you click Apply.
	Select None if you do not want to configure DNS servers. If you do not configure a
	DNS server, you must know the IP address of a computer in order to access it.
LAN TCP/IP
IP Address	Type the IP address of your HomeSafe in dotted decimal notation 192.168.1.1
	(factory default).
IP Subnet Mask	The subnet mask specifies the network number portion of an IP address. Your
	HomeSafe will automatically calculate the subnet mask based on the IP address
	that you assign. Unless you are implementing subnetting, use the subnet mask
	computed by the HomeSafe 255.255.255.0.
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 HomeSafe 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 HomeSafe 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-2Band RIP-2Msends the routing data in RIP-2 format; the difference being
	that RIP-2Buses subnet broadcasting while RIP-2Muses 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-1or IGMP V-2or 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.
