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.
When you install the Gateway, you will not need to use the
PPPoE software on your PC.
When you install the Gateway, you will not need to use the
dialup VPN on your PC anymore.
The Gateway will automatically ‘dial on demand’ PPPoE or PPTP
and obtain data/time via NTP.
1 Static 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)
2 Dynamic 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.
3 PPPoE (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)
4 PPTP (DSL or Cable)
PPTP is mainly used by some European service 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)
