Re°ew butto°

It is possible to renew the IP address by

PPP IP Address

The IP address to be used during a PPP

session. This defaults to the IP address

of the

interface.

Use the followi°± static IP address

(Default)

This is the IP address of your

Modem on your local network. This IP

address is speciﬁed on all computers

on your network as the Gateway IP

address. The IP address is also the IP

address you type into your browser lo-

cation bar to login to your modem’s web

interface.

Note:

If Server and Relay are turned off you need to assign IP addresses within

the same range to the PCs connected to the modem else they will not

be able to communicate with the modem.

For example, if your mo-

dem’s Ethernet interface address is 192.168.1.1 with a subnet mask of

255.255.255.0 you need to assign static addresses starting at 192.168.1.2

up to 192.168.1.253.

If you disable the DHCP server in the Modem you will need to either manually (stati-

cally) assign IP address information to each computer or use another device/com-

puter as DHCP server.

Note:

It is not recommended that you have more than one DHCP server enabled

on your network.

Option

Description

Server O°:

Enables the DHCP server.

Start IP:

Sets the start IP address of the IP ad-

dress pool.

E°d IP:

Lease time:

The lease time is the amount of time an

IP address issued by the DHCP service

of your modem is valid before being

updated. If all ﬁelds are 0, the allocated

IP address will be effective forever.

E°able DHCP Relay:

Allow PCs on LAN to request IP address

from other DHCP server.

The Connection setup page requires you to choose the correct settings to work with

your ADSL connection as speciﬁed by your ISP. The screen will add or remove non-

applicable choices as you change options. There are a few main settings you will

need to conﬁrm with your ISP before you can complete this page, these are;

•

Type of Connection (e.g. PPPoE, PPPoA, Static, DHCP, Bridge, CLIP)

•

Username & Password (usually only required for PPPoE or PPPoA types)

•

VPI & VCI (usually VPI=8 and VPI =35)

•

Authentication (Usually AUTO will work otherwise check with your ISP)

Most other choices on this screen are personal preference and not critical to getting

your connection working.

Note:

The Username & Password you need to type in here is for your ISP’s ac-

count and it will be supplied to you by your ISP.

Description

Optio°s:

NAT / Firewall

NAT (Network Address Translation al-

lows you to share the public IP ad-

dress assigned to the WAN (Wide Area

Network) interface of your modem with

multiple clients on your LAN (Local

Area Network). NAT also acts as a basic

ﬁrewall. The ﬁrewall feature protects the

PCs on your LAN from malicious attacks

from people on the Internet (e.g. DOS

attacks).

VLAN ID

If you decide to share this connection

with a VLAN, this ﬁeld will be enabled

and you need to select your VLAN ID.

For example, if you have your Ethernet

interface in LAN Group 1 and your USB

interface in LAN Group 2 you can create

a VLAN for both groups to access each

other.

Priority Bits

Set the priority bit of the Ethernet frame

if using a VLAN.
