Hi Holdings,
Two things to keep in mind when designing VPN's on the PIX:
1. You can never bounce a packet of a PIX interface, hence PIX doesn't do any redirects for packets out the same interface.
2. As long as we have a Route for the packets terminating on the Outside, to go to the DMZ interface, we should be fine.
