the Internet

Before you begin

By default, the ADSL Barricade automatically assigns all required Internet settings to your PCs. You need only to configure the PCs to accept the information when it is assigned.

Note:

If you have connected your PC via Ethernet to the Barricade system installed on your PC.

In some cases, you may want to assign Internet information manually to some or all of your computers rather than allow the ADSL Barricade to do so. See Assigning static Internet Information to your PCs for instructions.

Assigning static Internet Information to your PCs

In some cases, you may want to assign Internet information to some or all of your PCs directly (often called statically), rather than allowing the ADSL Barricade to assign it. This option may be desirable (but not required) if:

You have obtained one or more public IP addresses that

•

you want to associate with specific computers (for example, if you are using a computer as a public web server).

You maintain different subnets on your LAN (subnets are
