WEC 7 - 防火墙 [英] WEC 7 - Firewall

问题描述

我正在尝试在我的WEC 7设备中实施防火墙。我能够在我的操作系统中构建防火墙组件，现在尝试更改防火墙的默认配置。

I am trying to implement firewall in my WEC 7 device. I am able to build the firewall component in my OS and now trying to change the default configuration of firewall.

具体来说，我希望能够允许我的设备通过DHCP获取IP地址，是特定端口上的ping-able和主机webserver。这几乎是我所需要的，休息应该被阻止。

Specifically, I want to be able to allow my device to obtain IP address via DHCP, is ping-able and host webserver on a specific port. That is pretty much all I need and rest should be blocked.

从MSDN文档来看，似乎能够做到这一点，我会有使用WFP功能修改现有过滤器。但我找不到任何好的示例源代码。任何指针？

From MSDN documentation, it seems that to be able to do the above, I will have to modify existing filters using WFP functions. But I can't find any good example source code. Any pointers?

谢谢，

推荐答案

<另外，我的理解是默认情况下防火墙在通过SYSGEN_FIREWALL包含在操作系统中时启用，但似乎不是。

Also, my understanding was that firewall is enabled by default when included in the OS via SYSGEN_FIREWALL, but it seems like it is not.

对于WEC 7之前的OS版本，我认为它是通过防火墙启用/禁用API完成的，但是对于WEC 7，它似乎全部通过WFP完成。

For OS versions prior to WEC 7, I think it was done through Firewall enable/disable API but with WEC 7 it appears all is done via WFP.

我们如何启用默认的防火墙设置，因为从我所看到的仅包括我操作系统中的防火墙不能启用它，我无法弄清楚如何启动/停止它。

How do we enable even the default firewall settings because from what I can see just including the firewall in my OS does not enable it and I can't figure out how to start/stop it.

谢谢，
