load balancing problem

[Mohamed HADROUJ (Gmail)]

Hi,
when  entring the following command : ipvsadm -L -c -nI I get this result :

IPVS connection entries
pro expire state       source             virtual            destination
UDP 04:57  UDP         10.11.11.225:32875 10.11.11.230:1812
10.11.11.19:1812

Every request sets the counter to 5:00
Thank you for your help
