Adding IP Addresses & Gateways

Hi,

I am about to do a fresh install of Ispconfig on a dedicated server with Debian minimal installation as my OS.
I want to run several domains under Ispconfig, each with its own IP address.
In total I have four IP's on two gateways with different subnet like this:

IP1 1.22.333.4 gateway 1.22.333.1 subnet 255.255.255.224
IP2 1.22.333.12 gateway 1.22.333.1 subnet 255.255.255.224

IP3 1.22.888.77 gateway 1.22.888.1 subnet 255.255.255.248
IP4 and another ip-address

The first IP address is the address of my server, 2,3,4, etc. are assigned later.
My server has one ethernetcard (eth0)

Will ISPconfig automaticly take care of the routing, dns etcetera when I enter the IPs in the admin interface? Or do I need to change e/n/interfaces, DNS etc. manually before installing ISPconfig?

My DNS file is currently setup as an slave, so that BIND9 (ISPconfig) could handle this. I can change this setting in the panel of my ISP (Hetzner), to create a standard zone file, with the credentials of ISP1.

So far I only installed the OS, I did test out ISPconfig with 1 IP address before. but I got conflictions with SSL certificates, thats why I want to have 1 IP per domain. What would be the course of action to adchieve this?

Thanks in advance,
Martend

 

Thanks you for answering Till,

Will do this first, but I asume further configuration, DNS zones etc, is also needed since the auto-configuration is not recommended? (just to be shure ),
