JGroups clustering across subnets should work ! Make sure that
- the switch/router connecting the subnets forwards IP multicast packets 
between the subnets
- you set UDP.ip_ttl to be 2 or higher (if IPv4 is used)
- you have correct default routes for the other subnet in each subnet


That should do it...
