I was wondering if VTI's are officially supported on PIX Firewalls? I managed to get a VTI on a 2811 connected to a PIX, but when it does, all internet traffic from users behind the PIX fails. I can still do what I want across the tunnel, but it kills internet traffic. Does anyone have any pointers/guides? Cisco is kind of blank on this subject. Everything talks aobut VTi to VTI, not VTI to PIX.
