I assume that the PPTP clients that cannot connect are residing behind the PIX-501. If yes, then open the following ports and protocols on the ACL of the PIX-501. This ACL will be applied to the outside interface of the 501.


access-list outside_acl permit udp any any eq 1723

access-list outside_acl permit gre any any


That should do it.

Will port 47 need to be allowed also? If so what commands will I need to use? Thanks for your help on this.

It is NOT port 47. It is protocol 47. The access-list is:


access-list outside_acl permit 47 any any


OR THE SAME THING CAN BE ENTERED AS:


access-list outside_acl permit gre any any
