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:

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)

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.

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)

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)
