Configure VPN with cisco 678 running dhcp and nat

[Potter]

I am struggling with configuration of VPN on win2k server
that is connected to 678 router using dhcp and nat
however the clients on the network are static ip's and I
added nat entries for certain ports specifying the server
internal ip and the router outside ip. I can connect with
TS and PCANY with the xternal IP but I want to utilize VPN
and establish a VPn connection and then access those apps
with the internal IP.

Configure the RRAS server for remote access. Check the config by making a
VPN connection to it from a LAN client.

When this works, forward tcp port 1723 from the router to the RRAS
server's LAN IP. Also check that the router allows GRE (IP protocol 47) in
both directions (inward and outward).

From a remote client you should now be able to make a VPN connection by
using the router's public IP. The VPN traffic will be forwarded through the
LAN to the RRAS server.

I can get you connected to VPN with that trusty ole Cisco 678 I have the
same Router

At CBOS Prompt type without quotations

"set nat entry add internalIP 1723 tcp"
"set nat entry add interanlIP 0 47"

As far as my problem is concerned I have a client with the same netmask and
same subnet as server its connecting to, I need a work around to connect
with these IP settings. I can connect, but cannot browse or ping IP once
connected.
