Question

我的设置：一个Hazelcast docker container在boot2docker vm中运行（托管在Windows上，是的，端口5701被转发）。这是Hazelcast 3.4.2。

当我尝试将一个简单的java客户端连接到这个hazelcast实例时，我得到了一个：

总结一下：客户端似乎看到了集群及其成员，但接下来会发生一些阻止连接按预期工作的事情。

有什么想法吗？

我想您的问题是，Hazelcast节点的内部和外部地址是不同的，即使可以通过NAT到达节点，也拒绝接收公共地址的请求。您可以使用配置来配置公共地址：http://docs.hazelcast.org/docs/3.4/manual/html-single/hazelcast-documentation.html#public-address（参见上面的示例）。
