Ephemeral Port
Starting Ephemeral Port
Rev 1 Dec. 17
Description
Enable or Disable the Ephemeral Port feature
Disable—The source port in packets the AirLink gateway receives from a connected
•
device and then sends out is not changed. The source port assigned to the packet
when it was created in the customer's connected device is used. (default)
Enable—The AirLink gateway changes the source port on all outgoing NATed UDP
•
packets, using the range configured in the Starting Ephemeral Port field.
This field appears only when the Ephemeral Port field is set to Enable. It allows you to set
the starting port range used by a LAN device as the source port for over-the-air (OTA)
destinations using NAT.
Note: This field is intended for advanced users only. In most cases, use the default
value.
The NAT for the LAN device uses a range of 1000 ports as source ports for OTA
destinations beginning with the configured Ephemeral port. Options are:
1024 (default)–64535
•
If you have a network with multiple LAN devices that are sending data to the same server
and the server is not receiving data from one (or more) of the devices, it may be because
the Mobile Network Operator has a WAN firewall that is blocking the ports used by the
NAT for over-the-air (OTA) destinations. This field enables you to avoid the blocked ports
by changing the source port range used to send the data. For example, some users have
found that changing the starting port to 42000 has resolved the issue.
Note: The ephemeral port setting does not affect any outbound traffic initiated by the
device such as Location reports, Events Reporting, Device Initiated ALMS connection,
etc.

RADIUS Framed Route

If you have a private APN that is authenticated with a unique user name and
password through a RADIUS authentication server, Framed Route enables you to
associate a pool of IP address (for example a /24 subnet) with that user name,
effectively creating a remote branch of a private corporate network. Refer to the
RADIUS specifications for more details.
For an AirLink gateway to work effectively with Framed Route, set the following
two fields on the LAN > Ethernet screen to "Enable":
• Accept Unsolicited Traffic—Enabling this field allows a device on the
corporate network to dial out to a device connected on the LAN side of the
AirLink gateway.
• Turn Off NAT—Enabling this field allows traffic from the LAN side of the
AirLink gateway to flow back to the corporate network.

USB

The AirLink gateway is equipped with a USB port that increases the methods by
which you can send and receive data from a connected computer. You can set up
the USB port to work as either a virtual Ethernet port or a virtual serial port, or
