I need to telnet from the public Internet into a box that is sitting behind a PIX and is using a private IP address. I have already used NAT to translate an available public IP to the internal/private IP of this box. However, the problem is that this box does not have the routing setup to properly reply to clients connecting to it from a source IP from the public Internet. Is there a way that I can somehow make clients with public Internet address look like they are being sourced from a private address? In this way the box would be responding to a private IP instead of the true source which is not reachable.
