In the process of setting up ipsec tunnels between 7206 (ios 12.3.x) and a remote Pix (6.3.3). I have been told conflicting things about the ability to terminate tunnels to a loopback. Ideally, we would terminate to a public ip on the remote pix's physical interface and to a loopback, with a public ip, on the 7206. Can anyone point me in the direction of good documentation on this subject? Does anyone know if it will work correctly?
