Symptoms

Consider the following scenario:

  • You run FTP Service 7.5 in Internet Information Services 7.5 (IIS 7.5) on a computer that is running Windows 7 or Windows Server 2008 R2.

  • You create a FTP site.

  • You create a custom logging module that uses the IFtpLogProvider.Log method to record FTP activities for the FTP service. The IFtpLogProvider.Log method uses the RemoteIPAddress and LocalIPAddress members of an FtpLogEntry class instance to obtain IP address information.

  • You use a remote client to connect to the FTP site.

In this scenario, the custom logging module logs the value of the RemoteIPAddress and LocalIPAddress members incorrectly. Additionally, the following are the incorrect values that are logged:

  • The recorded value for the RemoteIPAddress member incorrectly contains the IP address of the computer that runs the FTP service.

  • The recorded value for the LocalIPAddress member incorrectly contains a null value.

Note The correct value for the RemoteIPAddress member contains the IP address of the remote client. The correct value for the LocalIPAddress member contains the local IP address that the client used.
