dynamips

I am setting up a dynamips/dynagen lab and am wondering if there is any way to get traffic to route out one tap devices, go into the lab, and come back to a tap device on the same machine. I have tried host specific routes as well as removing the route created when I give the tun device an ip via ifconfig. With both of these, traffic always preferes the attached devices and won't go through my lab.

Any way to make this work without a separate machine or vm?
