FTP port appears to be dynamically assigned

561 Views

Hi experts,

I have a scenario where XI is picking up a file from a FTP network folder with the communication channel specifying the IP, port=21 and user/password credentials. If the FTP site opens up only port 21, this does not work. Only when FTP site opens up all ports, the communication works. The administrator of the FTP site mentioned that he is seeing requests with dynamically assigned ports come in from XI (none of them being 21). Has anyone encountered the same? For now, all ports are being kept open but we are trying to investigate how to control the port number so that only one or a few ports can be kept open rather than unrestricted access. Is there some setting or profile parameter in XI due to which the "21" that we mention as port in the communication channel is bypassed for some other dynamic value at runtime?

Thanks

JB
