PPTP access-list problem PIX

[rasoftware]

I have a PIX configured (6.3) configured as a PPTP endpoint which works fine. I am doing some testing on an internal PPTP server. Every time I add a new translation rule and ACL (different public IP to interface) I get NULL RULE on the PDM. Is is not possible to terminal PPTP and port forward on the same PIX even when using a different public IP?

eg.

Outside PPTP endpoint 195.x.x.1

NAT 195.x.x.200 -- internal PPTP server

This document discusses the configuration required on the Cisco Secure PIX Firewall to allow a Point-to-Point Tunneling Protocol (PPTP) client to connect to a PPTP server through Network Address Translation (NAT).

Refer to Configuring the Cisco Secure PIX Firewall to Use PPTP in order to configure a security appliance to accept PPTP connections.
