could not get connection using ConnectionFactory which from remote jndi lookup; just using RemoteConnectionFactory

the server side configuration:

<connectors>
<netty-connector name="netty" socket-binding="messaging" />
<netty-connector name="netty-throughput" socket-binding="messaging-throughput">
<param key="batch-delay" value="50"/>
</netty-connector>

</connectors>
<acceptors>

<in-vm-acceptor name="in-vm" server-id="0"/>

my client side jndi.properties
java.naming.factory.initial=org.jboss.naming.remote.client.InitialContextFactory
java.naming.provider.url=remote://222.92.115.15:4447
java.naming.security.principal=uname
java.naming.security.credentials=pword

when i use jndi to lookup an ConnectionFactory,I got the factory like this:
HornetQConnectionFactory [serverLocator=ServerLocatorImpl [initialConnectors=[org-hornetq-core-remoting-impl-netty-NettyConnectorFactory?port=5445&host=10-50-50-13], discoveryGroupConfiguration=null], clientID=null, dupsOKBatchSize=1048576, transactionBatchSize=1048576, readOnly=false]

but when i use the factory to create an connection,it failed:
Caused by: HornetQException[errorCode=2 message=Cannot connect to server(s). Tried with all available servers.]

it used ip 10.50.50.13 to create an connection, but i want to use ip 222.92.115.15 to create an connection.
I have not found any place to configure this ip for RemoteConnectionFactory
