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 47. 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 47.
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
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 47.
Configuring a computer to use DHCP
DHCP is a protocol that allows a computer to obtain its IP address from a DHCP server on a network when the computer connects to the network. This type of IP address is called a dynamically assigned IP address because it can change when the computer disconnects from the network and later
The satellite modem incorporates a DHCP server (always enabled) to assign IP addresses to computers that connect to it. The modem can assign private IP addresses or public IP addresses, depending on the service plan purchased by the satellite modem customer.
In most cases, DCHP should be enabled on a computer or computers that connect to the satellite modem so the computer(s) can ask for and receive an IP address (private or public) from the satellite modem DHCP server.
DHCP should be disabled on your PC if you have purchased a service plan with a public IP address(es) and want to use a public IP address.
