Configuring Direct Relay and Network Edge Devices for True Source IP Detection

Configure your direct relay and all network edge devices on the page Settings > Inbound/Outbound > True Source IP as follows:

Steps

  1. Click Add.
    The Add Direct Relay IP Address/IP Group page displays.
  2. Enter the IP address for the direct relay device to the email appliance, or specify the existing IP group to use for your direct relay.
    By default, the direct relay hop number is 1, because it is the closest network device to the email appliance.
    Important: The IP address or group that you enter here must not already be defined in the Trusted IP Addresses group (Settings > Inbound/Outbound > True Source IP) or appear in the connection control Allow Access List (Settings > Inbound/Outbound > Connection Control).
  3. In the field Check for header, enter header text to match for true source IP detection.
    If this field is empty, the message Received field is analyzed for the true source IP.
  4. Add the network edge device IP address and hop number to the email appliance; click Add Network Edge.
  5. Click OK.
    The settings are saved.
