ThurayaIP Satellite Modem User Guide
Private Local IP Address: This setting allows you to change the lower two
octets of the terminal’s local gateway address. Changing this address
will change the address of the wMMI and the base address for the
Ethernet DHCP server. This subnet must remain unique from the WLAN
subnet address being used.
DHCP Server: The DHCP server for Ethernet can be enabled or disabled
as needed. If disabled, a local static IP addressing scheme must be
used by connected Ethernet devices. This setting has no impact on the
WLAN operation which uses a dedicated DHCP server.
Netmode: This command allows for NAT or Relay Mode to be selected.
The NAT (Network Address Translation) mode allows multiple devices to
be connected via the Ethernet, USB and WLAN ports. This is the default
operating mode. Relay Mode is used for special situations where a
single local device needs to be assigned the same address as the
Global IP Address assigned to the user terminal. The connected device
is assigned a LAN address initially, but with a very short DHCP lease time.
When the Global IP Address is assigned to the
Thuraya
IP
it is flowed
through to the connected device via a DHCP address reassignment. All
WAN traffic flows through to the single connected device with no port
or address translation. Relay Mode requires DHCP to be enabled.
Global IP Address:
Obtain Address Automatically: If this button is
selected
,
Thuraya
IP
uses an IP address automatically assigned by the network during
the period when the Modem connects to the network.
Static IP Address: If this button is
selected
, the Modem uses the IP
address you enter in the associated IP Address field. You should
check this box and enter an IP address only if directed to do so
by your Service Provider.
DNS:
Obtain DNS Address Automatically: If this button is
selected
, the
Thuraya
IP
uses a Primary Host Domain Name Service (DNS)
automatically assigned by the network during the period when
the Modem connects to the network.
Static DNS Host: If this button is
selected
, the Modem uses the DNS
address you enter in the DNS Address field. You should check this
box and enter an IP address only if directed to do so by your
Service Provider.
DMZ Host: If you wish to route incoming network originated IP traffic to a
specific connected device, enter that device’s IP address in this
