5.5 Configuring LAN Static DHCP – ZyWALL
This table allows you to assign IP addresses on the LAN to specific individual computers
based on their MAC Addresses.
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address
is assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02.
Select a device, and then click Configuration > LAN > Static DHCP.

DESCRIPTION
Type the IP address of the ZyXEL device in dotted decimal notation. 192.168.1.1
is the factory default.
The subnet mask specifies the network number portion of an IP address. The
ZyXEL device automatically calculates the subnet mask based on the IP address
that you assign. Unless you are implementing subnetting, use the subnet mask
computed by the ZyXEL device, which is 255.255.255.0.
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 ZyXEL 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.
The RIP Version field controls the format and the broadcasting method of the
RIP packets that the ZyXEL 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.
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.
