LAN Setup

LABEL

DESCRIPTION

DHCP

DHCP

If set to

Server

, your ZyXEL Device can assign IP addresses, an IP default

gateway and DNS servers to Windows 95, Windows NT and other systems that

support the DHCP client.

If set to

None

, the DHCP server will be disabled.

If set to

Relay

, the ZyXEL Device acts as a surrogate DHCP server and relays

DHCP requests and responses between the remote server and the clients. Enter

the IP address of the actual, remote DHCP server in the

Remote DHCP Server

field in this case.

When DHCP is used, the following items need to be set:

Client IP Pool

Starting Address

This field specifies the first of the contiguous addresses in the IP address pool.

Size of Client IP

Pool

This field specifies the size or count of the IP address pool.

Primary /

Secondary DNS

Server

Enter the IP addresses of the DNS servers. The DNS servers are passed to the

DHCP clients along with the IP address and the subnet mask.

Remote DHCP

Server

If

Relay

is selected in the

DHCP

field above then enter the IP address of the

actual remote DHCP server here.

TCP/IP

IP Address

Enter the IP address of your ZyXEL Device in dotted decimal notation, for

example, 192.168.1.1 (factory default).

IP Subnet Mask

Type the subnet mask assigned to you by your ISP (if given).

RIP Direction

RIP (Routing Information Protocol) allows a router to exchange routing

information with other routers. Use this field to control how much routing

information the ZyXEL Device sends and receives on the subnet.

Select the RIP direction from

None

,

Both

,

In Only

and

Out Only

.

RIP Version

Select the RIP version from

RIP-1

,

RIP-2B

and

RIP-2M

.

Multicast

Select which version of IGMP the ZyXEL Device uses to support multicasting on

the LAN. Multicast packets are sent to a group of computers on the LAN and are

an alternative to unicast packets (packets sent to one computer) and broadcast

packets (packets sent to every computer).

IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to

establish membership in a multicast group. The ZyXEL Device supports both

IGMP version 1 (

IGMP-v1

) and

IGMP-v2

. Select

None

to disable it.

Any IP Setup

Select the

Active

checkbox to enable 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 ZyXEL 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 ZyXEL Device’s LAN IP

address can connect to the ZyXEL Device or access the Internet through the

ZyXEL Device.
