Juniper SRX210,如何为 192.168.1.151 本地 IP 启用端口 554、9001?

我一直在努力解决这个问题,但仍然无法解决。我有一台 192.168.1.151 PC,它打开了 554 和 9001 TCP/UDP。但我需要公开访问它。在我的 Juniper Srx210 中,我也有以下配置。但我不明白它为什么不起作用。

答案1

您的 DNAT 看起来不错,但您还没有创建防火墙策略来允许流量。您应该编辑信任区域的地址簿并为内部的主机添加条目,然后创建一个与这些目的地和应用程序匹配的从区域不信任到区域信任的策略。您可以参考内置应用程序,也可以创建自己的应用程序,但这是在配置顶部的自己的部分中完成的,而不是在安全节下。这是一个策略示例,为了达到这个级别,我输入了“编辑从区域不信任到区域信任的安全策略”。然后输入以下内容。

policy exchange {
    match {                             
        source-address any;
        destination-address [ exchange1 exchange2 ];
        application [ junos-https junos-smtp junos-http junos-imap junos-ping junos-imaps junos-pop3 ];
    }
    then {
        permit;
        count;
    }
