I am hoping to setup a L2TP connection between two 2811's with 12.4 for a school project. Ideally, the two routers will negotiate and handle all session setup for the L2TP. I am hoping to do this without any configuration on my clients on either sides of the router. The purpose is to test the L2TP compared to IPSec for similar network setup. All literature I read seems to point to my clients needing to initiate a PPP connection across the L2TP between the routers. Is it possible to setup a straight L2TP tunnel between two routers so that it is transparent to the clients on both sides of the router?

Thanks for any advice!
