3. CONNECTING TO YOUR ISP
Before you can configure the Router, you need to know the IP allocation
method used by your ISP. There are four different methods that the Router
can use to connect to the Internet, as described below. For all methods, you
need to know the VPI (Virtual Path Identifier), VCI (Virtual Channel Identifier)
and the Encapsulation (LLC or VC Mux). The Router defaults for the VPI and
VCI should cater for most ISPs. Your ISP can provide you with the required
information.
1. PPPoE
To configure the gateway, you will need to know the user name and password
to log in to your ISP account. If you have been using a PPPoE client on
your computer, you can disable it as it is no longer needed. If your ISP
provides you with a static IP address, enter this IP address in the Internet
Settings section of the Router Web interface. Otherwise, your ISP will
automatically assign your Router an IP address.
2. PPPoA
This is similar to PPPoE but is used mainly in the UK. To configure the
gateway, you will need to know the user name and password to log in to
your ISP account. If your ISP provides you with a static IP address, enter
this IP address in the Internet Settings section of the Router Web interface.
Otherwise, your ISP will automatically assign your Router an IP address.
3. Bridge Mode for a Single Computer (RFC 1483 Bridging Mode)
In this mode, the Router is set into a bridging mode to connect the LAN
and WAN networks. Traffic is limited between the two networks based on
hardware addresses and so limits the LAN side to a single computer.
4. Routing Mode over ATM (RFC 1483 Bridging Mode)
Routing mode over ATM means that the Router has a fixed IP address to
connect to the Internet. Your ISP will provide the Router with a fixed IP
address, the subnet mask and the ISP's gateway address. You need to
enter this information in the Internet Settings section of the Router Web
interface.
