do you only have additional ips or a new subnet ? in both ways this should work .. edit your /etc/network/interfaces and add Code: up ip addr add yourip/32 dev eth0 down ip addr del yourip/32 dev eth0 of course you have to insert yourip and the network adapter if nessesary then restart the service networking
It's the same subnet. In /etc/network/interfaces, do I just add another line: # The primary network interface auto eth0 iface eth0 inet static address [original ip address] netmask ... gateway ... iface eth0:0 inet static address [new ip address] netmask ...
Is there anything else? I added those lines in /etc/network/interfaces and added the ip address in ISPConfig.
you have to restart the networking service .. on debian you do that by Code: /etc/init.d/networking restart probably works for ubuntu too. But be sure you have edited the interfaces file correctly .. since you wont be able to reach the server at all if theres a mistake .. im saying this due to experience
