VLAN traffic on a simple layer3 cisco switch

I have a small business switch, SF300 series from Cisco, and I would like to set it up with 2 VLANs that should have no interaction.  I will treat them as if they were 2 physically separate switches.  There will be a few PCs and servers on each VLAN and each will connect to its own router/firewall.  By default the layer3 switch wants to route all IP traffic between the 2 VLANs, what is the most straightforward way to stop all interVLAN traffic?  Thanks.

That was my best guess and I can see where to setup simple ACLs in the GUI, but cannot see how to assign them to a VLAN.  There is a binding option that looks like it is for assigning ACLs to ports.  Is that the best or only method?

Can you telnet into it or connect through the console?

Yes.  I even got into some limited CLI mode to assign IPs to the VLANs.

it seems that these small business devices do not support applying a access-list to a VLAN.

The access lists are applied to the interface. You then create allow or deny subsets you want to permit or deny on the interface
