we have a windows nlb cluster running. jboss is working fine on both machines. the only prob we have is the cache sync using mutlicast. the cluster members do not receive the multicast packet from the ohter member, so cache is not sychron.
we've uninstalled NLB and tried again, now the communication between the two clients does work.
does anybody have an idea, why with the software loadbalancer jgroups does not work?
