I need to use my PIX 506E as a PPTP VPN server with authentication aginst my Active Directory intrigrated RAIDUS server (Windows IAS). Below is my configuration that is currently working:

I am able to connect to the PPTP VPN just fine with my domain login, but when I do, anytime traffic is passed I see the CPU utilization of the PIX go up to and stay at 100%. I have tried with both PPTP fixup protocol on and off, it does it either way. What is going on?
