Problems with Clustering

Hello,

I am trying to enable openfire clustering on version 4.4.1 using Hazelcast Plugin 2.4.2. My config file on both machine is:

<?xml version="1.0" encoding="UTF-8"?>
<hazelcast xmlns="http://www.hazelcast.com/schema/config"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://www.hazelcast.com/schema/config
           http://www.hazelcast.com/schema/config/hazelcast-config-3.12.xsd">
    <group>
        <name>openfire</name>
        <password>openfire</password>
    </group>
    <network>
        <port auto-increment="true" port-count="100">5701</port>
        <outbound-ports>
            <ports>0</ports>
        </outbound-ports>
        <!-- The following enables multicast discovery of cluster members
                See http://docs.hazelcast.org/docs/3.12/manual/html-single/index.html#discovering-members-by-multicast
        -->
        <join>
            <multicast enabled="false">
                <multicast-group>224.2.2.3</multicast-group>
                <multicast-port>54327</multicast-port>
            </multicast>
            <tcp-ip enabled="false"/>
        </join>
        <!-- The following enables TCP/IP based discovery of cluster members
                See http://docs.hazelcast.org/docs/3.12/manual/html-single/index.html#discovering-members-by-tcp
        -->
        <!--
        <join>
            <multicast enabled="false"/>
            <tcp-ip enabled="true">
                <member>192.168.3.148:5701</member>
		<member>192.168.3.143:5701</member>
            </tcp-ip>
        </join>
        -->
        <interfaces enabled="false">
            <interface>192.168.3.*</interface>
        </interfaces>
        <ssl enabled="false"/>
        <socket-interceptor enabled="false"/>
        <symmetric-encryption enabled="false">
            <!--
               encryption algorithm such as
               DES/ECB/PKCS5Padding,
               PBEWithMD5AndDES,
               AES/CBC/PKCS5Padding,
               Blowfish,
               DESede
            -->
            <algorithm>PBEWithMD5AndDES</algorithm>
            <!-- salt value to use when generating the secret key -->
            <salt>thesalt</salt>
            <!-- pass phrase to use when generating the secret key -->
            <password>thepass</password>
            <!-- iteration count to use when generating the secret key -->
            <iteration-count>19</iteration-count>
        </symmetric-encryption>
    </network>
</hazelcast>

both ports on the 192.168.3.148 and 192.168.3.143 are open and accessible from each machine.
The machines do not seem to find themselves and I can see only one machine in the cluster interface.

I would appreciate if you could give me some advice.
Thank you

It worked for me now with this configuration:

            </multicast>
            <tcp-ip enabled="true">
                <member-list>

                    <member>192.168.3.143</member>
                </member-list>
            </tcp-ip>
        </join>
        <interfaces enabled="true">
            <interface>192.168.3.*</interface>
        </interfaces>
	</network>
</hazelcast>
