Same as http://www.howtoforge.com/forums/showthread.php?t=32647&highlight=siocaddrt Everything works, but in ISPConfig Control Panel > System > Server Config I checked Network Configuration and after "Save" and reboot I lost network connection. If I run /etc/init.d/network restart I get Reconfiguring network interfaces...SIOCADDRT No such process Failed to bring up eth0 done edit: sorry, bad address in gateway field but what about nameservers? They disappeared from /etc/network/interfaces and only one appeared in /etc/resolv.conf Default separator is " , " so everything should be ok.
The resolv.conf file is not managed by ispconfig, so you should have as many namservers listed there as you added in that file.
