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.
