Hi, I'm new to the list but I have gone through the FTP articles on the website. I've even contacted MS ISA support on this issue but they weren't able to help. Here is the issue: I am connecting to a secure FTP site from my AS400. The initial port is 6366 and the data connections use ports 6367-6416. I am able to make an SSL connection but when the data connection is attempted it dies. I am using a protocol rule; initial port is 6366 with secondary connections on 6367-6416 (inbound). I have tried packet filters, server publishing and nothing is working. Anyone have any suggestions on this? Tom
