Computer settings
For proper operation of the satellite modem, you may have to change certain settings on the computer that is connected
to the modem.
Instructions are provided for:
•
Configuring a computer to support DHCP
•
Configuring a computer to use a public IP address
•
Disabling a web browser's proxy connection
These procedures are explained in the sections that follow.
Understanding the modem address and computer address
The satellite modem and any computer or computers that connect to it must each have their own identifying network
address. This network address is known as an
IP address
. An IP address may be
dynamic
, meaning that it can change,
or
static,
meaning that it is fixed—it does not change. An IP address may also be public (or
routable
), meaning that it
can be used on the Intranet. A
private
IP address works on an internal network but not over the Internet. However, to
gain access to the Internet, private addresses may be converted by a network address translation (NAT) service to a
public IP address that can be used on the Internet. Both private and public addresses can be dynamic or static, although
typically a private IP address is dynamic and a typically a public IP address is static.
Both the modem and a connected computer can have either type of address—private or public. The type used depends
on requirements a customer might have and their service plan. A public IP address or addresses are available only if
they are specified in the service plan. Typically home users use a private IP address, but some home users use a public
IP address.
To find specific address information, go to the System Control Center System Information page
Figure 18: Terminal
Status page (top part)
on page 26. Scroll down until you see Addressing in the left column. Look at the first three
parameters in the Addressing field, as shown in the following two examples.
Private IP addresses
Figure 28: Example of Addressing parameters showing available private IP addresses
on page 49 is an example of
System Information page address parameters for a satellite modem with a service plan that provides private IP addresses.
Figure 28: Example of Addressing parameters showing available private IP addresses
In this example, the satellite modem is assigned a private IP address (LAN Port Address) of 192.168.0.1.
