We are having problems configuring NAT on our Cisco 1921 Router. Below is the running config. The problem we're having is for example our FTP server 192.168.1.16, cannot be accessed from its outside IP address, which is NATed on the router. The server is verified to be up and running and when we do a show debug ip nat, we see the router is translating outside users attempting to access the ftp server to it's correct internal IP address. Please help.
