6 Router Configuration using the web interface
ADSL Modem
This section describes how to configure the way that your BT
Micro connects to the Internet. Your ISP determines what type
of Internet access you should use and provides you with any
information that you need in order to configure the Internet
access to your BT Micro.
Your BT Micro needs the following address information in order
to access the Internet:
IP address and
subnet mask:
The IP address and subnet mask
assigned to your WAN interface.
Default gateway: The gateway address that identifies the
ISP server through which your Internet
connection will be routed.
DNS servers: The Dynamic Name System (DNS)
servers used by your ISP to dynamically
assign addresses to each of the
computers attached to your LAN.
In most cases, you will not need to configure your BT Micro
with these addresses because your ISP is likely to use an
Internet access type, which automatically assigns addresses to
your BT Micro.
Types of Internet Access
PPP Internet access – your BT Micro uses a Point to Point
Protocol (PPP) to carry data between your ISP and your
computer. To use PPP Internet access, you must enter a PPP
login username and password the first time to log on. The IP
addresses required to access your ISP’s Internet service are
automatically configured.
Your BT Micro supports two types of PPP – PPPoE (over
Ethernet) and PPPoA (over ATM).
DHCP – your ISP uses a protocol called Dynamic Host
Configuration Protocol (DHCP) to assign addresses and
manage your BT Micro. The BT Micro is automatically assigned
the IP addresses that it needs to access the Internet.
Manual – you manually assign the addresses that your BT
Micro needs in order to access the Internet. Your ISP should
provide you with the necessary addresses.
Configuring your PPP DSL connection
If your ISP’s Internet service uses PPPoA or PPPoE you need
to set up a PPP login account. The first time that you login to the
Internet, your ISP will ask you to enter a username and
password so they can check that you are a legitimate,
registered Internet service user. Your BT Micro stores these
