Hi, I read the excellent wiki page about more clusters in the same network, see http://wiki.jboss.org/wiki/Wiki.jsp?page=TwoClustersSameNetwork The proposed solution use is based on the transport protocol UDP, ... it is possible to get a similare solution based on TCP ? Is also read the page about TCP on the jboss wiki (see http://wiki.jboss.org/wiki/Wiki.jsp?page=JGroupsTCP) but I don't see directly what to change to have two different clusters in the same network. Of course I think the first think is to define to different ClusterName... but then? ... define two different portRange ? for example, the first: <TCP bind_addr="192.168.1.3" start_port="7600" end_port="7800"/> and the second: <TCP bind_addr="192.168.1.4" start_port="7800" end_port="8000"/> Can somebody please help me?
