If I understand, the PPTP server is another machine on your LAN segment?

If that's right, did you try to activate the PPTP redirection on the
vpn_pptp.php page?

-> check "Redirect incoming PPTP connections to:"
-> then "Enter the IP address of a host which will accept incoming PPTP
connections."

Don't forget to add a rule to allow PPTP_USERS to pass on WAN interface...

That should work ;-)
