Our webservers are behind a NAT so that we may use an advanced firewall while using multiple webservers. This is fine and dandy aside from the fact that our DNS records are generated improperly, and we'd like to switch over from using Webmin's dns cluster management features to using cPanel's, as we're expanding and that would cut down our requirements for our intervention when a new account is created.

I've found the Template file, and changed it accordingly in both our webservers. This changes the A records fine, and directs pages to the servers, however, I've found that the cpanel, webmail, and ftp subdomains are still created using the site's registered IP, which, due to the NAT, is internal and not external. Where is the config file or template for those records?
