Trying to configure a cluster that uses only TCP but without a success, the ports been assigned correct to the transport but the nodes are not trying to discover each other, any advice ?.

Here is my configuration:

1) two 5.1 nodes on localhost.
2) run commands:
jboss-5.1.0.GA-node1\bin\run.bat -Djboss.service.binding.set=ports-02 -c all
jboss-5.1.0.GA-node2\bin\run.bat -Djboss.service.binding.set=ports-03 -c all


3)
Node - 1

<TCP singleton_name="shared-tcp"
start_port="7800" />
<TCPPING initial_hosts="localhost[7801]" port_range="5"
timeout="3000" num_initial_members="3" />



Node - 2
<TCP singleton_name="shared-tcp"
start_port="7801" />
<TCPPING initial_hosts="localhost[7800]" port_range="5"
timeout="3000" num_initial_members="3" />
