these terminals should be set to connect automatically. JRC
terminals can be managed by the S-Box and the S-Box will
configure the terminal for IP and initiate the connection
automatically when the “CONNECT” button is clicked.
Note that when using the JRC FB250 it is advisable to
override the automatic DNS by entering your provider’s DNS
server’s IP number (or Inmarsat’s DNS: 172.30.66.7)
manually.

Once all settings have been correctly entered click on “SAVE

Now this uplink setting can be selected from the “Uplink” menu on
the CONNECT page.
XI. Changing the Uplink Transport Protocol
The S-Box is configured to use either UDP or TCP/IP as uplink
protocols (data channel from the S-Box to the internet). There are
two advantages of using UDP.
1. Web browsing will be quicker as there is less handshaking
needed.
2. There will be a reduction in the data overhead on the uplink
channel – potentially saving some uplink costs.
However UDP protocol, although reliable over most links, has been
seen to be blocked by a few uplink providers' firewalls. So if you
choose to change the protocol to UDP, it is recommended that each
of the uplinks is tested to make sure that all three arrows on the
'connect' page are highlighted when you connect. This will confirm
that there is no problem with your uplink provider's firewall, and that
you can reliably use UDP as the transport protocol. Note that this
setting only applies when you are using the Wired Ocean downlink; it
has no effect when the downlink is set to 'none'.
To change the Uplink Transport Protocol:
1. Click on the “SETTINGS” tab and then the “GENERAL” tab.
2. Click on “Advanced Settings” (move the side bar up or down
until you see the contents).
3. Select TCP or UDP. The default is UDP.
