Website works external but not internal

Hey Guys,

I am facing a Little Problem here. I am working in an AD internal Network. I have a Windows Server 2012 as Domain Controller and serving as DNS Server for the internal Clients. Another virtual Machine is my virtualmin. It has the IP Address 192.168.7.112. I am using Split DNS, so the Windows DNS Server resolves WEBSITE.MYDOMAIN.COM to 192.168.7.112 and in the Internet it is solved to my pulic static IP Adress.

Virtualmin is configured only to the internal IP Addresses (see Screenshots) and I have a certain Destination NAT Rule on my Firewall which is passing all incoming traffic on port 80 on my external IP to my internal IP of my virtual min on port 80.

From external the Webpage is loading fine, but from internal it is not loading at all. If i do an nslookup to my WEBSITE.MYDOMAIN.COMit resolves to the internal IP Adress of virtualmin correctly.

Anybody got any idea?

Cheers,
Niklas
