IOS 12.0 pptp config with Nat (yet another person wants to know)

Sorry for posting this but the stuff I looked at really did not help.
Sometimes I feel a little dense ; )

I have a 2000 server behind a 1601r with ios 12.0 This router is doing
NAT.

I am trying to have the router simply pass thru the PPTP stuff to the
win2k server so I can log into that with a VPN Client. I've checked the
VPN server and it is allowing connections when not going thru the
Cisco.

I have 1723 forwarded but can't figure out the GRE.
I am triing to come in on 199.104.99.99 (example address)

any help would save me some sleep!

Here is the config for anyone that would be so kind as to help:
