IP settings changed after release-upgrade - broadcast changed

I have an ISPConfig 3 on Ubuntu Server 10.04

It seems that IP setting has been changed after release-upgrade or by some other reason. My local IP setup is:

Server IP:

Doing "ifconfig" I get a "broadcast" I'm quite sure it used to be "" Is it wrong? And if, do I chance it at the shell or can it be done in ISPConfig 3 controlpanel?

Looking forward to your response :)

DHCP - Disabled...

Thanks for your response :o

DHCP is disabled in the webserver, yes... has been set to a static ip
DHCP in router is running in the range - And I made a static IP setup and portforwarding to the server ip

Solution for (broadcast changed) found! But! in the same section....
You got me thinking about the setup from the start! And therefore I clown'ed around a little more and found this:
ISPConfig 3 is not changing anything in /etc/network/interfaces by default as the network management feature is disabled in a config file. You must have anabled this manually in the ispconfig file and there you can disable the network configuration again.

And I did enable that function, due to the text regarding:
"The network configuration option is only available for Debian and Ubuntu Servers. Do not enable this option if your network interface is not eth0. etc..."

So thanks for that :o)

But in the same section "Server Config - Nameservers" these ip's is shown:

Found this after reading 486 sites ;)
Google's global DNS IPs,, and

..and this after reading 232 additional sites ;)
// If your ISP provided one or more IP addresses for stable
// nameservers, you probably want to use them as forwarders.
// Uncomment the following block, and insert the addresses replacing
// the all-0's placeholder.

forwarders {;;

So are these ip's ok? I have a nameserver myself and uses a secondary some other place. Do I replace ";" with my own? Or what is usually done?

Looking forward to any kind of response :o
