I have a little problem with remote access vpn using PPTP on a PIX 506E firewall. Actually i have a site-to-site vpn setup on the pix that connects to an ASA on the other side. When i tried to configure remote access PPTP vpn on the PIX, the clients can actually connect but cannot access the internal network behind the PIX. Cannot ping any machines inside, cannot access any server inside. I am attaching the PIX config, please help me out.
