Still the same thing no change: Hell, MSN whom we rarely ever see these days due to other duties helped me put the following config together on the exact same router I'm having issues with "and it worked: OK, I'll take another look at it tomorrow. Gotta be something simple. They are a blessing. I'm setting up a new Brother DW printer at the moment and have given up on vpn for the day have actually spent most of it studying for my "route" exam.

One suggestion is use different algorithms, especially if the remote end is not Cisco. Basically, phase 1 is completing on your router, it tries to notify other peer that it succeeded but that notify never makes it through and the remote end kills the connection. This also means that main mode has failed. The issue was that the phase 2 security lifetime association was globally configured on the cisco ASA as below:.
