Ok. 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.
