    I'm running ISPConfig 3.1.6 on Debian Wheezy with three machines.
    1. master/web/database
    2. e-mail
    3. DNS
    They are all on public IP addresses, but I want to move them behind the DMZ.
    If I understand correctly, I simply change the IP on the web/master/database server, set up my firewall, and reboot. Then everything works there.
    Unclear on what I need to do on the mail and DNS servers. Same thing? Is it that simple?
    Also, the database sync for ispconfig database. Do I give it the DMZ IP or the public IP, and how do I change that.
    Looks like, from the number or articles that popped up when I ran the search it might be a good place for a baby HowTo.
    Final question. I intend to set up XMPP. I have an XMPP server (ejabberd) that I manually configured a long time ago. When I tried to put that server behind the DMZ, XMPP stopped working; it needed another module I haven't figured out yet. I was going to go with your installation at a later date (after this move)
    So, my question is
    A. what do I need to do for each of these machines so they come up.
    B. What do I need to do so ISPConfig can talk between the master and slave. I understand the slaves are requesting updates (every hour) via, I assume, 3306.
    These are all production, so I can't have them down too long.
    Thank you,
    Rod

    Change the IP address in the network configuration file of the operating system and in /etc/hosts file. By using the internal address for the server names in /etc/hosts, you can instruct the system to route the MySQL connections from ISPConfig over the internal network.

    The ISPConfig slaves connect to the master once a minute trough MySQL, so the final step is that you edit the ispcsrv* users in mysql and set the new IP addresses there to allow connections again (use the user editor in phpmyadmin as the ispcsrv* users are complex users with permission settings in different sub-tables).
