General

Mode

Select

Routing

(default) from the drop-down list box if your ISP gives

you one IP address only and you want multiple computers to share an

Internet account. Select

Bridge

when your ISP provides you more

than one IP address and you want the connected computers to get

individual IP address from ISP’s DHCP server directly. If you select

Bridge

, you cannot use Firewall, DHCP server and NAT on the ZyXEL

Device.

Encapsulation

Select the method of encapsulation used by your ISP from the drop-

down list box. Choices vary depending on the mode you select in the

Mode

field.

If you select

Bridge

in the

Mode

field, select either

PPPoA

or

RFC

1483

.

If you select

Routing

in the

Mode

field, select

PPPoA

,

RFC 1483

,

ENET ENCAP

or

PPPoE

.

User Name

(PPPoA and PPPoE encapsulation only) Enter the user name exactly as

your ISP assigned. If assigned a name in the form user@domain

where domain identifies a service name, then enter both components

exactly as given.

Password

(PPPoA and PPPoE encapsulation only) Enter the password associated

with the user name above.

Service Name

(PPPoE only) Type the name of your PPPoE service here.

Multiplexing

Select the method of multiplexing used by your ISP from the drop-

down list. Choices are

VC

or

LLC

.

This field is not available if you set the WAN type to

Ethernet

.

Virtual Circuit ID

VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define

a virtual circuit. Refer to the appendix for more information.

These fields are not available if you set the WAN type to

Ethernet

.

VPI

The valid range for the VPI is 0 to 255. Enter the VPI assigned to you.

VCI

The valid range for the VCI is 32 to 65535 (0 to 31 is reserved for

local management of ATM traffic). Enter the VCI assigned to you.

IP Address

This option is available if you select

Routing

in the

Mode

field.

A static IP address is a fixed IP that your ISP gives you. A dynamic IP

address is not fixed; the ISP assigns you a different one each time you

connect to the Internet.

Select

Obtain an IP Address Automatically

if you have a dynamic

IP address; otherwise select

Static IP Address

and type your ISP

assigned IP address in the

IP Address

field below.

Subnet Mask

This option is available if you select

ENET ENCAP

in the

Encapsulation

field.

Enter a subnet mask in dotted decimal notation.

ENET ENCAP

Gateway

This option is available if you select

ENET ENCAP

in the

Encapsulation

field.

Specify a gateway IP address (supplied by your ISP).

The ZyXEL Device will try to bring up the connection automatically if it

is disconnected.

Connect on

when you don't want the connection up

all the time and specify an idle time-out in the

Max Idle Timeout

field.

Max Idle Timeout

Specify an idle time-out in the

Max Idle Timeout

field when you

select

Connect on Demand

. The default setting is 0, which means

the Internet session will not timeout.

DESCRIPTION

RIP & Multicast

Setup

This section is not available when you configure the ZyXEL Device to

be in bridge mode.

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

This field is not configurable if you select

None

in the

RIP Direction

field.

Select the RIP version from

RIP-1

,

RIP-2B

and

RIP-2M

.

Multicast

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).

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

used to establish membership in a multicast group. The ZyXEL Device

supports

IGMP-v1

,

IGMP-v2

and

IGMP-v3

. Select

None

to disable

it.

ATM QoS

ATM QoS Type

Select

CBR

(Continuous Bit Rate) to specify fixed (always-on)

bandwidth for voice or data traffic. Select

UBR

(Unspecified Bit Rate)

for applications that are non-time sensitive, such as e-mail. Select

rtVBR

(real-time Variable Bit Rate) type for applications with bursty

connections that require closely controlled delay and delay variation.

Select

nrtVBR

(non real-time Variable Bit Rate) type for connections

that do not require closely controlled delay and delay variation.

Peak Cell Rate

Divide the DSL line rate (bps) by 424 (the size of an ATM cell) to find

the Peak Cell Rate (PCR). This is the maximum rate at which the

sender can send cells. Type the PCR here.

Sustain Cell

Rate

The Sustain Cell Rate (SCR) sets the average cell rate (long-term)

that can be transmitted. Type the SCR, which must be less than the

PCR. Note that system default is 0 cells/sec.

Maximum

Burst Size

Maximum Burst Size (MBS) refers to the maximum number of cells

that can be sent at the peak rate. Type the MBS, which is less than

65535.

MTU

The Maximum Transmission Unit (MTU) defines the size of the largest

packet allowed on an interface or connection. Enter the MTU in this

field.

For ENET ENCAP, the MTU value is 1500.

For PPPoE, the MTU value is 1492.

For PPPoA and RFC 1483, the MTU is 65535.
