This is also what I have explained to you in several posts. I can do port forwarding, port range forwarding, etc. in my sleep. The WAN IP is port forwarded to this domain only. To make it easier on you, I will be glad to fill up this entire server with files, isp vhost files, screenshots, whatever you need to show you that this domain is specifically forwarded to this LAN IP and this domain only. If ISPConfig is running on the main server IP...example, that being
192.168.1.5 and ISPConfig loads fine, then you create an alias eth0:0 with your Public IP forwarded to 192.168.1.6 (where eth0:0 includes the information for this IP), then you add it in the config panel, then ISPConfig creates a
100-domain.com.vhost file with this IP, then the site should launch. What would you like for me to send you indicating that ALL of this is configured in this way?
