DESCRIPTION
LAN TCP/IP
IP Address
Type the IP address of your ZyXEL Device in dotted decimal notation. 192.168.1.1
is the factory default. Alternatively, click the right mouse button to copy and/or
paste the IP address.
IP Subnet Mask
The subnet mask specifies the network number portion of an IP address. Your
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.
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 ZyXEL Device 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 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.
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 interoperability between IGMP version 2 and
version 1, please see sections 4 and 5 of RFC 2236.
DHCP Setup
DHCP
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows
individual clients (workstations) to obtain TCP/IP configuration at startup from a
server. Unless you are instructed by your ISP, leave this field set to Server. When
configured as a server, the ZyXEL Device provides TCP/IP configuration for the
clients. When set as a server, fill in the IP Pool Starting Address and Pool Size
fields.
Select Relay to have the ZyXEL Device forward DHCP requests to another DHCP
server. When set to Relay, fill in the DHCP Server Address field.
Select None to stop the ZyXEL Device from acting as a DHCP server. When you
select None, you must have another DHCP server on your LAN, or else the
computers must be manually configured.
IP Pool Starting
Address
This field specifies the first of the contiguous addresses in the IP address pool.
Pool Size
This field specifies the size, or count of the IP address pool.
DHCP Server
Address
Type the IP address of the DHCP server to which you want the ZyXEL Device to
relay DHCP requests. Use dotted decimal notation. Alternatively, click the right
mouse button to copy and/or paste the IP address.
