hi guys. Need some help configureing m cisco 827 to allow pptp passthrough traffic. I have configured the acl to allow port 1723 and gre traffic from any source/destination in/out on the dialer interface. I can physically see that traffic going through the router in the logs but still unable to make the connection. I have also tested this with a different (non-cisco) router and works fine. nat is configured on the router. I have also run wireshark and can see the pptp traffic going from and to my PC from the site. Any help would be greatly appreciated.
