Access ISPConfig from only one domain
Hi all.. I'm a new user to ISPConfig and oh boy am I ever pleased. The HowTo's provided here were beyond helpful in getting my system up and running. Amazing.
Here's my setup. I'm running this all from 1 computer with 1 external IP and 1 internal IP. I've managed to get everything working perfectly. What I want to do though, is make it so port 81 is only accessible through a single domain. As it stands, you can access any ISPConfig page from any domain hosted on my server. Making it only accessible from a single domain would be ideal for creating a central page for all clients/users.
Anybody have any ideas on how to do this? I'm sure it's pretty simple..
