I have OpenSuse 10.2 which configured on virtual server. So many ip adress are assigned to the same IP interface.

I have the same problem and after a little search I have solved it.

First edit to /etc/sysctl.conf and
Add
net.ipv4.conf.eth0.log_martians = 0
Make sure your NIC is eth0 or change to appropriate one (see your nic from ifconfig command)
then start sysctl ;

$: /etc/rc.d/boot.sysctl start

To add sysctl in boot use

$: chkconfig boot.sysctl on
