已经部署了2008多的32位
  使用Citrix标准的Web服务器
  NetScaler的ISAPI（在NetScaler的是一个
  负载平衡器），在所有情况下
  客户端IP地址记录在
  标准的IIS日志。在一个新的项目，我
  被要求部署2008 R2，
  配置了IIS 7.5与相同
  我是如何在过去的配置IIS 7.0，
  而这一次的客户端IP
  返回在负载平衡器地址
  日志。这里是怪异的一部分，我
  安装了高级日志，它是
  示出了客户端IP地址
  正确，所以ISAPI是尽
  工作。用Google搜索这一个死亡
  并且可以使用一些建议。

Have deployed many 2008 32 bit standard web servers using the citrix netscaler isapi (the netscaler being a load balancer), in all cases the client IP address is logged in the standard IIS logs. On a new project I was asked to deploy 2008 R2, configured IIS 7.5 identically with how I configured IIS 7.0 in the past, this time however the client ip is returning the load balancer address in the logs. Here is the weird part, I installed "advanced logging" and it is showing the client IP address properly, so the isapi is doing its job. Have googled this one to death and could use some advice.

我还发现ISAPI筛选器模块，但不能让它工作：<一href=\"http://devcentral.f5.com/weblogs/Joe/archive/2009/08/19/x_forwarded_for_log_filter_for_windows_servers.aspx\">devcentral.f5.com/x_forwarded_for_log_filter_for_windows_servers

I also found ISAPI Filter module but cannot make it work: devcentral.f5.com/x_forwarded_for_log_filter_for_windows_servers

推荐答案

问题在源$ C ​​$ C文件中使用HTTP_CLIENT_IP代替REMOTE_ADDR解决。

Problem solved by using HTTP_CLIENT_IP instead of REMOTE_ADDR in sourcecode files.

有关IIS日志的问题是由安装IIS高级日志模块解决的建议这里。此外，我得到了错误503：服务不可用。安装高级日志之后，但通过授予读写权限大家的Program Files文件\\ IIS文件夹解决了这个，开始失败的应用程序池

The problem about IIS Logs was solved by installing IIS Advanced Logging module as suggested here. Also I got error "503: Service Unavailable" after installing Advanced Logging but solved this by granting read-write permissions to Everyone for Program Files\IIS folder and started failed application pools.

另一种解决方案建议这里是：

Another solution suggested here is:

在负载下的NetScaler
  平衡，服务，然后下
  高级选项卡，在设置检查
  对于使用源IP的框，
  客户端IP，然后在头字段
  CLIENT-IP

On the NetScaler under "load balancing", "Services" then under the advanced tab, under settings, check the box for "Use Source IP" and "Client IP" then in the Header field "CLIENT-IP"
