Parallel connection with Sophos XG and MX68

[emmaozoms]

Hello Guys,

Please I need a best practice approach to set up my MX68 to connect to a Sophos XG in a parallel. The Sophos is the upstream and has a static IP address. I have also assigned a static IP address to the MX. The subnet of both devices is 192.168.20.0/24. I want to establish the below.

There's no reason that topology won't work. Provided the Sophos XG has a route configured to know what to send down to the MX. That said, is there a purpose of placing the MX behind the XG?
If it's just for terminating Site-to-site VPN connections, you might be better off configuring it in VPN Concentrator mode.
