ASA 5512-X & SG300 Layer 3 mode - question about routing

Hey,

So basically the ASA 5512-X is handling traffic from the inside to the outside and the SG300 is doing routing between the VLANs

But the ASA 5512-X is also routing our VLANs to our DHCP server, is this something the SG300 is supposed to be doing our is it fine for the ASA 5512-X to be doing this?

Reason I ask is because I read its best practice to have the firewall do no internal routing and to strictly keep it as a "firewall"

So this is how it would work if I created a new VLAN

1. Create DHCP Scope on Win DHCP Server

2. Create VLAN in SG300

3. Apply any ACL between the new VLAN and other in SG300

4. Route the new VLAN in ASA 5512-X to the switch EG (route inside 172.25.30.0 255.255.255.0 10.230.1.254)

5. Nat the new VLAN so that it can access the internet on the 5512-X
