    Hi, Yahyaa, and welcome to the UTM Community!

    We have no idea of the complexity of your topology, so we have to guess at what you want to do.  If you want the UTM to switch all of the traffic, yes, you will need the same VLANs defined on UTM.  There you will only need firewall rules allowing desired traffic.  Two things to be aware of with WebAdmin:

    WebAdmin automatically creates routes between the subnets and IPs defined on Interfaces of the UTM.
    The UTM is a stateful firewall, so you only need rules allowing requests to flow, response packets are automatically accepted.

    Cheers - Bob
