clustering problem with openfire 3.82 and Hazelcast1.06

Hi,

I'm trying to setup two openfire 3.82 installed in redhat in same LAN network.

I have enable clustering using hazelcast 1.06 and this my config for this both machine.

<group>

        <name>openfire</name>

        <password>openfire</password>

    </group>

    <management-center enabled="false"/>

    <network>

        <port auto-increment="true">5701</port>

        <join>

            <multicast enabled="false">

                <multicast-group>224.2.2.3</multicast-group>

                <multicast-port>54327</multicast-port>

            </multicast>

            <tcp-ip enabled="true"/>

<hostname>150.xxx.xxx.7:5701</hostname>

<hostname>150.xxx.xxx.8:5701</hostname>

</tcp-ip>

            <aws enabled="false"/>

        </join>

After i have enabled the clustering, it showing one local node only for both machine.

please show me some guide

Thanks
