Changing Meraki MX to a 3-party firewall

[garonson]

Hi

I have a customer with with a existing Meraki network that has a Meraki MX as firewall and a lot of meraki layer-2 switches an AP's behind the firewall.

The customer have decided to change the firewall to a 3-party firewall(in this case a Fortigate FW) but would like to keep the meraki lay-2 equipment . 

If we open for all the access to meraki cloud through the new firewall for the layer-2 devices will we be able to see and manage the equipment? Will the layer-2 network keep configuration? What will we loose?

Best regards Goran Aronson

Hi @garonson , this will work and is a pretty standard setup.  Ensure the Forti is configured to allow the required ports and IPs out to the Meraki cloud.

Thank you! I thought so but I have never done it!

@garonson  This will 100% work, one network I manage has MS, MV, MR and MT all sitting behind a Fortigate. As Darren mentioned just make sure that the required outgoing WAN rule allows the required ports. These can be found by logging into the dashboard and under the help menu and selecting firewall info.
