spring发布RMI服务，多网卡问题

服务器有两个网卡，一个内网，一个外网

Spring xml配置如下：

	<context:property-placeholder location="classpath:/config/app.properties" />
	<!-- 客户端RMI服务 -->
	<bean id="appPush" class="cn.com.sinosoft.ebusiness.messagePush.service.server.support.RMIServiceImpl"/>
	<bean id="appPushMsg2Client" class="org.springframework.remoting.rmi.RmiServiceExporter">
		<property name="service" ref="appPush" />
		<!-- 定义服务名 -->
		<property name="serviceName" value="appPushMsg2Client" />
		<property name="serviceInterface" value="cn.com.sinosoft.ebusiness.messagePush.service.server.RMIService" />
		<property name="registryPort" value="${ServicePort}" />
		<property name="registryHost" value="${ServiceRegistryIp}" />
	</bean>

 在app.properties强制spring发布rmi服务注册IP为内网的IP（10.120.20.197），结果发布的时候出现下面异常：

如果注释掉这一行

<property name="registryHost" value="${ServiceRegistryIp}" />

 发布的时候从日志上看是外网的IP，现在发布服务的时候要强制绑定到内网的IP上。求解决方法，谢谢！
