This section refers only to the LAN screen, but the information is applicable for 
the LAN, WLAN, and DMZ screens.
TCP/IP
IP Address
Type the IP address of the device in dotted decimal notation.
IP Subnet Mask
The subnet mask specifies the network number portion of an IP address. Unless 
you are implementing subnetting, use the “natural” subnet mask, which is usually 
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 device broadcasts its 
routing table periodically. When set to Both or In Only, it incorporates the RIP 
information that it receives; when set to None, it does not send any RIP packets 
and ignores 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 device 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 interpretability 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 device 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 device’s LAN IP address can 
connect to the device or access the Internet through the device.
