Consider the following scenario:
- You assign multiple IP addresses on a network adapter of a muti-home computer.
- You specify the adapter to use an FtpWebRequest instance in the PASV mode to connect to FTP servers by using the Microsoft .NET Framework 2.0.
- You set the ServicePoint object in the instance to use a new IP address instead of the previous IP address of the adapter.
In this scenario, the control channel of the connection uses the new IP address but the data channel of the connection uses the previous IP adapter.Â
This problem occurs because a method in the
System.Net.FtpControlStream class does not read the value of the
ServicePoint.BindIPEndPointDelegate property.
