But this error does not occur on my other CentOS 5 box (mailserver, non-xen) which also has 2 nics for 2 public ip segments. There input-nic is always = outputnic. And I have done nothing special to achieve this (pure "linux magic"). That's why I "blame" bridges - they are the most notable difference between these two machines. - Jussi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15 C * 00250 Helsinki * Finland Tel. +358 9 493 981 * Mobile +358 40 771 2098 (only sms) jussi.hirvi at greenspot.fi * http://www.greenspot.fi
