So I currently have a private ip address on the outside interface of my PIX. It connects to a switch, then to the router. The router has static mappings to forward subnet x to the Pix outside private ip address. No problems, its all working great. I know an trying to implement a VPN solution. I have installed and configured everything on the pix for this, and it works. I have connected clients to the switch outside the firewall, connect to the private ip, and we are good.
Now I need to make it possible to access this VPN connection from the internet. How in the world do I get the Outside interface to answer calls to an IP address other then the one on the outside interface?
I cannot change my outside interface ip address to a public one, to much to try and change, as well as more security issues.
