Force external communication between two interfaces on same box

I need to send data between two network interfaces on the same linux box. The problem is that I need the packets to go through a switch rather than being internally routed so that I can analyse the packets.

Is there a way to force the packets to go out on to the network rather than being internally routed?

hopefully it will work if the IP-addresses are hidden behind different bridge devices and assigned to virtual interfaces moved into separate network namespaces; it is tricky to configure this properly but it should work then
