    Configured Automatically from the Hub This Appendix explains how to configure manually using the CLI parameters that for most SatLink systems are configured automatically by the Hub NMS when the SatLink VSAT enters the network for the first time. Do not configure any of these parameters manually unless being instructed to do so by the Hub operator, as wrong configuration may break IP connectivity for the SatLink VSAT.

  • Page 160 Note that when the internal SatLink DHCP server is enabled, the SatLink VSAT will configure the hosts on its LAN to use the SatLink VSAT as the primary DNS server, and its own DNS client‘s primary DNS server as the secondary DNS server. This is done in order to let the hosts use the DNS Forwarder of the SatLink VSAT to reduce the time for DNS lookups and especially improve the speed of Web browsing.

    The VSAT tunes to the transport stream of the Forward Link that it has pre-configured as the ―start-up‖ Forward Link. There it reads the NIT. The NIT PID value is hard-coded in the SatLink VSAT. In the NIT, the VSAT finds tuning parameters for accessing the satellite and Forward Link transport stream containing the RMT.
