Smile How-to create physical connection for a Multiserver Setup for ISPConfig 3

Hi guys,

I have read this article: A Multiserver Setup With Dedicated Web, Email, DNS And MySQL Database Servers On Debian 5.0 With ISPConfig 3 but I have not seen any physical network connection analysis. I have a technical questions:

1. Which is the best way to connect a basic network solution to the web?
2. How the physical network is connected between themselves?
3. Which are the main IPtables rules?

Attachment:
network: I have created a little pdf diagram.

There is no special network topology needed. Use e.g. a 1GBit switch and connect all your servers to that switch. Then either connect the switch to the internet or put a router between the switch and the internet depending on your internet connection.

Hi Till,

but in this way all the servers are reachable directly by the web. Is a good idea create a direct connection between each server and the web?

If I connect the switch directly with the public ip cable to the uplink port, are all the servers reachable by the same Ip from the web?

ISPConfig 3 handles the IpTables rules in this case?

thanks

The servers in a hosting setup provide services that shall be accessed from the internet, so they have to be connected to the internet.

You need one public IP address per server. If you have only one IP address, then you have to install a router between the internet and your servers.

I could have 4 IP addresses, one for each server.
So I have to set the Public IP during the configuration of the Debian/ISPConfig 3?

Does ISPConfig 3 handle them. If yes, how?

thanks

No, ispconfig does not handle ip routing as you describe.

Like till said;

You will have to have four public ip addreses

Each server will have it's own private ip address

You should have a router that will handle the forwarding of each public ip to each private ip.

On installation of the os etc onto each machine you should refer to it by it's own private ip. But when you want to make connections to it, via the public ip. (don't quote me on that last line!)
