[Bug] Deployment issues related to internal and external network connectivity

### Before Creating the Bug Report

- [x] I found a bug, not just asking a question, which should be created in [GitHub Discussions](https://github.com/apache/rocketmq/discussions).

- [x] I have searched the [GitHub Issues](https://github.com/apache/rocketmq/issues) and [GitHub Discussions](https://github.com/apache/rocketmq/discussions) of this repository and believe that this is not a duplicate.

- [x] I have confirmed that this bug belongs to the current repository, not other repositories of RocketMQ.

### Runtime platform environment

centos 7

### RocketMQ version

4.9.6|5.1.3

### JDK Version

11

### Describe the Bug

For a single-node deployment of RocketMQ, both the NameServer and Broker are deployed on a machine in the DMZ zone, which has both internal and external network IP addresses. Other internal network machines can only recognize the internal IP, while external network machines can only access the external IP.

If the `brokerIP1` in `broker.conf` is configured as the external network IP, internal network machines fail to obtain the topic routing information.

Conversely, if `brokerIP1` is configured as the internal network IP, external network machines will similarly report an error of failing to obtain the topic routing information.（RocketMQ单机部署，namesvr和broker都部署在DMZ区域机器，此机器有内外网两个IP地址，其他内网机器只能识别内网IP，外网机器只能访问外网IP。 如果将broker.conf中brokerIP1配置为外网IP地址，内网无法获取到topic的路由信息。 如果是将brokerIP1配置为内网IP地址，外网机器又会同样提示无法获取topic的路由信息。）
