FortiSwitch for remote access (as FortiAp) ?

Hi,

We have a remote office which is connected by a normal internet access. Before we go to Fortigate, we had Checkpoint Appliance and the remote office was connected through an UTM-1 Edge (hardware VPN or some sort of).

By what can we replace this UTM-1 Edge ? Actually we have done a VPN Software but it's not a good solution.

We want all the traffic from the remote office go to our main office, we don't want to split traffic at the remote office (like internet vs intranet). We have on the remote office only 4 PC and a printer.

I think FortiAp could be a solution, but we don't want any Wifi !

So a FortiSwitch can do the same or not ?

Or should we go to another smaller Fortigate ? => I think to expensive and more complex to manage

Thanks in advance
