Solved: How do I access FortiExtender IP from different VLAN/Subnet?

This article describes steps to access the FortiExtender IP from a different VLAN/Subnet, such as by using a ping or SSH.


FortiExtender, FortiGate, FortiExplorer.


A managed FortiExtender has only one default route to the FortiGate.
When FortiExtender is used with a SIM, two default routes exist on FortiExtender – one for LTE and one for LAN.

To connect to the FortiExtender from a different VLAN or subnet, it’s necessary to create a static route on the FortiExtender.

To do this, connect to the FortiExtender CLI and add a static route on FEX to the PC or Server from which to establish a connection such as ping, ssh, http, https.

#config router static
edit 1
set status enable
set dst (The PC/Server Network ID)
set gateway <fgt-intf-gateway> (IP of the FortiGate interface connected to FortiExtender)
set device <exiting intf> (PORT of the FortiExtender connected to FortiGate)

For example:

Connect to the FortiExtender CLI and add a static route on FEX to the PC or Server from which to establish a connection。

Note: Ensure that the FortiExtender port allows the necessary connection. For example: http, https, ping, ssh, or telnet.

Interface configuration example:

# config system interface
edit lan
set type physical
set status up
set mode static
set ip
set mtu 1400
set allowaccess http https ping ssh telnet
