Special notices

• For FortiExtender 511F devices, the Telstra modem must connect to an LTE/5G network following the first attach request.

• For FortiExtender 511F devices, the Telstra modem requires that a PDN be set for each and every LTE data plan.

• Not all receivers can receive SMS notifications. Be sure to adjust the receiver sequence to ensure that the first receiver always gets SMS notifications.
• Upon reboot, FortiExtender will try to discover the FortiGate or FortiEdge Cloud that manages it, depending on your existing configuration. Because of this, there might be a short delay before the device reconnects to the FortiGate or FortiEdge Cloud.
• In order for FortiExtender to forward syslog messages to a remote syslog server, the syslog server and the FortiExtender LAN port must be part of the same subnet.

• FortiExtender and FortiGate share the same LTE IP in WAN-extension mode. To distinguish local services from FortiGate services, you must configure FortiExtender to use different ports. Otherwise, all traffic to these default services will be sent to FortiExtender locally instead of the FortiGate.

• To avoid a known Quectel RACH issue on FEX-511F, Fortinet has disabled T-Mobile 5G Band n41 (see Known issues).
