Internet Settings Before you can configure the Gateway, you need to know the IP information allocation method used by your ISP. There are four different ways that ISPs can allocate IP information, as described below:

1Static IP Address (DSL or Cable)

The ISP provides the IP addressing information for you to enter manually. To configure the Gateway you will need to know the following:

■IP Address

■Subnet Mask

■ISP Gateway

■DNS address(es)

2Dynamic IP Address (DSL or Cable)

Dynamic IP addressing (or DHCP) automatically assigns the Gateway IP information. This method is popular with Cable providers. This method is also used if your modem has a built in DHCP server.

3PPPoE (DSL only)

If the installation instructions that accompany your modem ask you to install a PPPoE client on your PC, then select this option. To configure the Gateway you will need to know the following:

■Username

■Password

■Service Name (if required by your ISP)

When you install the Gateway, you will not need to use the PPPoE software on your PC.

4PPTP (DSL or Cable)

PPTP is only used by some European providers. If the installation instructions that accompany your modem ask you to setup a dialup connection using a PPTP VPN tunnel then select this option. To configure the Gateway you will need to know the following:

■Username

■Password

■VPN Server address (usually your modem)
