Static Routing Problems Involving NAT

I have a NT 4.0 Server which needs to establish an VPN connection on an outside network. This server is located on the inside interface of NAT. I have created static translation routes for ports 1723,80,443,110,and 25. PPTP also requires GRE (General Router Encapsulation) protocol 47 to connect properly. How do I create a static nat route to direct protocol 47 into the desired private address of the server?

Re: Static Routing Problems Involving NAT

Read “Does Cisco NAT support all application traffic?” at http://www.cisco.com/warp/public/cc/pd/iosw/ioft/iofwft/prodlit/iosnt_qp.htm. Add an access-list for GRE similar to:access-list nnn permit gre host x.x.x.x host y.y.y.y
