Ubuntu 12.10 Multiserver

[ChrisZ]

I have four VPSs on which I want to deploy a multiserver ISPConfig3 installation. This is my plan:

Server 1: ISPConfig with hosting, mail and DB only for my domain.
Server 2: Primary Nameserver
Server 3: Secondary Nameserver
Server 4: Web, Mail and DB for resellers & clients

I've tried following "Installing A Multiserver Setup With Dedicated Web, Email, DNS And MySQL Database Servers On Debian 5.0 With ISPConfig 3" but there are obvious differences in how I want to configure my system. There are also obvious differences between Debian 5.0 & Ubuntu 12.10 in how to install/configure some items.

Could I just follow "The Perfect Server - Ubuntu 12.10 (Apache2, BIND, Dovecot, ISPConfig 3)" for servers 1 & 4, obviously joining server 4 to the multiserver setup? The nameservers are pretty easy to figure out.

Thank you,
Chris
