your LAN; in other words, all (up to 25) computers on the LAN have access to and
may connect to that ISP and therefore the Internet. You may wish to review the
profile for this ISP connection to determine if you would like to make any changes.
For instructions, refer to “Editing Service Provider Profiles.”
ISP Versus Private
Network
There are two types of service providers you may configure on your LAN Modem,
an ISP and a Private Network. A description of each follows.
When to Select ISP
Choose ISP when you wish to set up a direct connection to the public Internet, via
an Internet Service Provider.
When to Select Private Network
Select Private Network when you wish to connect directly to a remote, private LAN
such as a corporate network. For instance, if you want to dial into your main office
from home in order to access the servers at your office for email, printing, etc.,
then select private network as the type of additional service provider to configure.
If the private network provides the option of accessing the Internet through their
connection, and you want to reach the Internet through your corporate LAN (as
opposed to a direct connection to an ISP), then choose that option when
configuring your private network parameters.
Setting Up a Connection
to an ISP
This section describes setting up your 56K LAN Modem for Internet access.
Before You Begin
Before you begin, you will need the following information from your ISP:
■
Telephone number(s) you must dial to access this ISP
■
User ID and password
■
DNS IP address(es). This information is required only if your ISP does not
provide an address dynamically.
