There are 253 available private IP addresses that can be assigned to computers connecting to the satellite modem. These
addresses are in the range from 192.168.0.2 to 192.168.0.254 (the Last Usable IP Address).
Public IP address
Figure 29: Example of Addressing parameters showing one available public IP address
on page 50 is an example of
System Information page address parameters for a satellite modem with a service plan that provides one public IP address.
Some service plans provide multiple public IP addresses.
Figure 29: Example of Addressing parameters showing one available public IP address
In this example, the satellite modem is assigned the public IP address (LAN Port Address) 97.73.73.65. The modem’s
DHCP server has only one public IP address to assign to a connecting computer: 97.73.73.66 (the Last Usable IP Address).
For instructions on configuring a public IP address on your computer, see the applicable section in
Configuring a
computer for a public IP address
on page 58. Find the section that applies to your computer operating system.
Multiple public IP addresses
If a service plan provides more than one public IP address, the range (or difference) from the LAN Port Address to the
Last Usable IP Address will be greater than one. For example, if the LAN Port Address is 97.73.73.65 and the Last
Usable IP Address is 97.73.73.70, the range (or difference) is 5, meaning there are five available public IP addresses.
If you don't know the modem’s public IP address…
To access the satellite modem when the service plan provides a public IP address, you need to know the public IP address
of the satellite modem (the LAN Port Address). If you do not know the LAN Port Address (and you cannot access the
System Information page), you can set a
link local
address on your computer as explained below:
1.
Use the Windows Control Panel on the connected computer to open the Local Area Connection Properties dialog
and then the Internet Protocol (TCP/IP) Properties dialog. If you need more specific instructions, see
Configuring a
computer for a public IP address
on page 58.
2.
In the Internet Protocol Properties dialog, click Use the following IP address.
3.
Enter the following:
a) In the IP address field, type
169.254.10.10
.
b) Typically the Subnet mask field auto-populates to
255.255.0.0
. If it does not, enter this value manually.
c) In the Default gateway field, type
169.254.0.1
.
d) In the Preferred DNS server field, type
66.82.4.8
.
e) Click
OK
twice to close the Internet Protocol Properties dialog and the Network Connections dialog.
4.
With the computer configured as instructed above, type
169.254.0.1
in your browser address window to open the
System Control Center.
If you click the link on the System Control Center home page for the System Information page, you can read the
modem’s IP address in the Addressing section. The LAN Port Address is the modem’s IP address.
5.
Record the LAN Port Address and the Last Usable IP Address.
Now you can enable DHCP on your computer (by selecting Obtain an IP Address automatically in the Internet
Protocol Properties dialog). Then, the modem will dynamically assign a public IP address to the computer.
Alternatively, if you want to assign a particular public IP address to your computer, you can set that public IP address
on your computer. To configure the public address, see
Configuring a computer for a public IP address
on page 58.
