This is my same exact problem. Right at that point that it is securing the channel it stops and the remote disconnects. My setup, is: W2K/ISA dials out to an ADSL. The Internal IP is: 192.168.5.55, the external is 192.168.6.166. When I connect on the 192.168.6.x network, and I initialize the dial-out connection, I am able to connect. I will be working more with this today. Any help is appreciated. Thanks.
