I'm having some diffuclty trying to setup our 831 to allow access to one of our systems via the Internet.
I have attempted this with setting up NAT.
I tried the following:
ip nat source static tcp 172.16.1.16 2000 interface ethernet 0 2000
Just to note we only have one IP address which is dynamic.
I'm not sure as of why I can't access the system. I have checked to make sure that the port number 2000 is accessible through our provider, which it is.
Attached is our configuration.
In advance I greatly appreciate the time taken to look at this post and reply,
