Hi there,
I'm experiencing some ddos (udp,tcp,syn,httd) for days now to my server ip and therefore I wanted to change the main server ip.
I've put the nameservers and all sites to a new ips, set the hosts file to the new ip but still there's the old IP listed as Main Server IP.
At the Show IP's tab it says "[Main Address]" for that ip and cause of that I cannot remove it.

How can i change that [Main Address] to a new ip so I finally can delete that old ip and null route it.

Greetings

The new ip is already set as shared IP for virtual hosts but as main adress there's still the old ip, how to change that?
