java.rmi.ConnectException：连接拒绝主机：<public IP>

Question

我正在使用 Cisco Netflow Collector 软件，它一直在按预期收集 netflow 数据，直到服务器管理员禁用 iptables 并且安全管理员为服务器启用了防火墙。现在它给出以下异常。

收集器在 internal/private 服务器上运行，Cisco NFC 许可证绑定到 public ip，因此主机名设置为 public ip in /etc/hosts 文件

sec 管理员已允许端口 22 和 1099，但仍抛出上述异常。我需要更改服务器或防火墙中的配置吗？

此问题已通过使用使用私有 IP 生成的思科新许可证得到解决。感谢 Vishawanath 和 EJP 的帮助。
