Configuring Manage Switch behind Sophos RED-60 device

[OTK]

I would like to configure a manage switch that I can deploye behind Sophos RED-60 Red device. Anyway has exprience with this kind of setup. The Red deivce work has a dhcp to the branch office hosts that it is connected to. The is no configuration involved except for setting up the RED-60 in the RED Divice Zone on the Sophos GX firewall. Once you have the configuration set, you just plug an traffic is routed. So, that is really part of the problem. I have amanagement vlan in the main office. If I configure the same vlan in the branch office, how can I make sure that I can access the switch, frame from valns configure on the siwtch behind the RED device is routed?

Its all depends on your design, is the VLAN IP extended to Branch or not.

Basic switch config on respected VLAN on cisco switch (not sure what model of the switch here to suggest some config)

the Port connecting from Switch to RED-60 (can be trunk or Access port depending on requirement) - suggest having the trunk

When RED-60 connecting to main office using VPN - then you may have LAN IP address in the VPN Setup, so use one of the IP RED-60 Lan side, the same range IP you can use to manage Switch here, Since your Firewall handling DHCP  for end device, these Layer 3 switches should just act as Layer 2 switch with Management IP to manage the switch (you can choose one of the excluded IP from DHCP range of Lan side - example 192.168.1.1 RED-60 , you can use 192.168.1.2 (DHCP range 192.168.1.10- 192.168.1.254)

This is high level that I can think of...

or you can ask your network administrator how you can set up at branches.

Sorry for the late respond. I will try the suggestion and will let you know how it goes. And yes, the VLAN IP does extend to the branch and I am using Dell N3048EP-On Switch. Thank you for the guidance.
