VPI

:

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

already be configured.

VCI:

The valid range for the VCI is 32 to 65535. Enter the VCI assigned to you. This field

may already be configured.

ATM QoS:

Select

CBR

to specify fixed (always-on) bandwidth for voice or data traffic.

Select

UBR

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

VBR

for burst

traffic and bandwidth sharing with other applications.

PCR:

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.

SCR:

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

transmitted.

MBS:

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

Encapsulation:

ISP:

Select the encapsulation type your ISP uses from the

Encapsulation

list.

Choices vary depending on what you select in the

Mode

field.

If you select

Bridge

in the

Mode

field, select

1483 Bridged IP

.

If you select Routing in the Mode field, select PPPoA, 1483 Bridged IP, 1483 Router IP or

PPPoE.

PPPoE/PPPoA

User Name:

Enter the user name exactly as your ISP assigned.

Password:

Enter the password associated with the user name above.

Encapsulation:

select Bridge in the Mode field, select either PPPoA or RFC 1483.

select Routing in the Mode field, select PPPoA, RFC 1483, ENET ENCAP or PPPoE.

Multiplex: Select the method of multiplexing used by your ISP. Choices are VC or LLC.

Connection:

The schedule rule(s) have priority over your Connection settings.

Always on

: Select Always on Connection when you want your connection up all the time.

Connect on Demand:

Select Connect on Demand when you don't want the connection up

all the time and specify an idle time-out in the Max Idle Timeout field

Get IP Address:

Choose Static or Dynamic

Static IP Address:

Enter the IP address of ADSL Router in dotted decimal notation, for

example, 192.168.1.254 (factory default).

IP Subnet Mask:

The default is 255.0.0.0. User can change it to other such as

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

Gateway:

You must specify a gateway IP address (supplied by your ISP) when you use

1483 Bridged IP

in the

Encapsulation

field in the previous screen.

Network Address Translation:

Select

None

,

Many to One

or

Many to Many

from the

drop-sown list box. Refer to the NAT chapter for more details.

Dynamic Route:

RIP Version:

Select the RIP version from RIP-1, RIP-2B and RIP-2M.

RIP Direction:

Select the RIP direction from None, Both, In Only and Out Only.

Multicast:

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. The BiPAC

5200 Series supports both IGMP version 1 (IGMP-v1) and IGMP-v2. Select None to disable

it

4.2.2 LAN

A Local Area Network (LAN) is a shared communication system to which many computers

are attached and is limited to the immediate area, usually the same building or floor of a

building.

Router Local IP

IP Address:

Enter the IP address of ADSL Router in dotted decimal notation, for example,

192.168.1.254 (factory default).

IP Subnet Mask:

The default is 255.0.0.0. User can change it to other such as

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

Dynamic Route:

Select the RIP version from RIP-1, RIP-2B and RIP-2M.

RIP Direction:

Select the RIP direction from None, Both, In Only and Out Only.

Multicast:

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. The BiPAC

5200 Series supports both IGMP version 1 (IGMP-v1) and IGMP-v2. Select None to disable

it

DHCP

DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual

clients to obtain TCP/IP configuration at start-up from a server.

DHCP:

If set to

Enable

, your BiPAC 5200 Series 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

disabled

, the DHCP server will be disabled.

If set to

Relay

, the BiPAC 5200 Series 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.

Starting IP Address:

This field specifies the first of the contiguous addresses in the IP

address pool.

IP Pool Count:

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

Lease Time:

The current lease time of client.

Primary 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.

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.

4.3 Advanced Setup

4.3.1 Firewall

Your router includes a firewall for controlling Internet access from your LAN and helping to

prevent attacks from hackers. In addition to this, when using NAT (Network Address

Translation) the router acts as a “natural” Internet

firewall, since all PCs on your LAN use

private IP addresses that cannot be directly accessed from the Internet.

Firewall:

~

Enabled:

As set in default setting

,

it activates your firewall function.

~

Disabled:

, it disables the firewall function.
