In this case, the FTP client binds the source port of the connection to a dynamic port. Due to this software issue when Extended Passive Mode is used, the ALG rule will match the control connection but may fail to learn the the dynamic port and so will not match the data channel traffic. This means that it can enforce the default port for an application, regardless of whether it is encrypted or not. On other ports, the FTP ALG won't work. though not sure if "nvram commit's" are a good policy to utilize. as Dlink Support suggested with the 1.
