Good day all,

I am running into some trouble trying to get a device behind a fortigate 80e on the LAN to talk to a device on the WAN at one of our remote sites

enter image description here

MQTT Device:

MQTT Broker:

Because of our security rules, we have to have these devices behind a Fortigate in order for them to talk to our MQTT Broker.

I created an Address for the MQTT Broker on the WAN on the Fortigate
enter image description here

I created an address for the MQTT Device on the LAN on the Fortigate
enter image description here

I Then created a firewall rule to allow the MQTT Device to talk to the MQTT Broker
enter image description here

After all this I set the MQTT software to look for the broker as the default gateway of the fortigate at My thinking is that it will hit this interface and then forward the traffic out of the WAN and onto the MQTT Broker, but it does not connect at all. I also look at the hit counter on the firewall rule configured on the fortigate and it says their is 0 bytes of traffic on it.

Please let me know if you can spot where I am going wrong. I have been on this for weeks to no avail.

Thank you!
