To use 1:1 NAT - 1:1 NAT Do you have to use the build_cpnat script? How do you enable 1:1 NAT? I see nothing that mentions NAT any where in my WHM. It says to manage maps use the Add a New IP Address link. There's nothing there when I click that. Nothing that mentions NAT.

  Hello :) I corrected the document URL you provided to the updated one here: 1:1 NAT In particular: When you install cPanel & WHM, the installer will detect whether your server is on a NAT-configured network. If the installer detects a NAT-configured network, your server will configure itself for NAT mode and attempt to automatically map local IP addresses to public IP addresses. The remaining part of the document should answer your question. Thank you.

  You may want to add something to the documentation about converting to a 1:1 NAT. All of the documentation seems to focus on "if 1:1 NAT is found during installation...". We had a server that was already up and running and it was converted to 1:1 NAT. I ran the script /scripts/build_cpnat and that seems to have fixed it. But that's not really that clear (at least to me) from the documentation.

  There is a section in that document titled "The build_cpnat script". Could you elaborate a little on what it could state to make it more helpful? Thank you.

  We don't support converting a system to 1:1 NAT. We only support setting up a fresh server in a NAT environment. You might be able to get it working by using build_cpnat, but there are no guarantees.
