4.1.2 Static IP Configuration of PCs Connected to the VSAT LAN
When the DHCP server in the SatLink VSAT is disabled, all PCs attached to the VSAT LAN must be
configured with static IP addresses that are within the address range of the VSAT subnet. The IP
configuration parameters to use for PCs connected to the VSAT LAN are supplied from the system
operator or service provider. Configure the IP address, Subnet mask, Default gateway, Preferred DNS
server, and, optionally, the Alternate DNS server as shown in Figure 16.
Ensure that the actual IP addresses supplied by the system operator/service provider are
configured and not the IP addresses in the example figure.

Example:
A host may have the following configuration: IP address 10.201.0.10, Subnet mask 255.255.255.0 and
default gateway 102.201.0.9, where the IP address of the default gateway should be the IP address of the
VSAT LAN interface.
4.2 Windows XP TCP/IP Configuration
Verify that the TCP/IP configuration is correct for PCs connected to the LAN you plan to use for your
SatLink VSAT. Click on the Start button in Windows, click Control Panel and then open Network
Connections. Right-click on the relevant Local Area Connection and select Properties. A new window
showing the Network Connection Properties will pop up. In the General submenu of this window, scroll
down, select Internet Protocol (TCP/IP) and then click the Properties button shown in Figure 17. Then
configure the PC client to obtain the IP address automatically from the VSAT IDU (section 4.1.1 ) or
configure the PC with a static IP address (section 4.1.2).
